Secondary structure dependence of amyloid-beta(1-40) on simulation techniques and force field parameters
(Wiley, 2021)Our recent studies revealed that none of the selected widely used force field parameters and molecular dynamics simulation techniques yield structural properties for the intrinsically disordered alpha-synuclein that are ... -
Zinc metalloprotease ProA of Legionella pneumophila increases alveolar septal thickness in human lung tissue explants by collagen IV degradation
(Wiley, 2021)ProA is a secreted zinc metalloprotease of Legionella pneumophila causing lung damage in animal models of Legionnaires' disease. Here we demonstrate that ProA promotes infection of human lung tissue explants (HLTEs) and ... -
Revisiting cu(II) bound amyloid-?40 and amyloid-?42 peptides: varying coordination chemistries
(Turkish Chemical Society, 2018)Metal ions and intrinsically disordered peptides amyloid-?40 and amyloid-?42 are at the center of Alzheimer´s disease pathology. Divalent copper ion binds to amyloid-?40 and amyloid-?42 peptides with varying coordination ... -
Current challenges and limitations in the studies of intrinsically disordered proteins in neurodegenerative diseases by computer simulations
(Bentham Science Publishers, 2020)Experiments face challenges in the analysis of intrinsically disordered proteins in solution due to fast conformational changes and enhanced aggregation propensity. Computational studies complement experiments, being widely ... -
Microbial peptidyl-prolyl cis/trans isomerases (ppIases): virulence factors and potential alternative drug targets
(Amer Soc Microbiology, 2014)Initially discovered in the context of immunomodulation, peptidyl-prolyl cis/trans isomerases (PPIases) were soon identified as enzymes catalyzing the rate-limiting protein folding step at peptidyl bonds preceding proline ... -
Polyketide synthase (PKS) reduces fusion of Legionella pneumophila-containing vacuoles with lysosomes and contributes to bacterial competitiveness during infection
(Elsevier Gmbh, Urban & Fischer Verlag, 2014)L. pneumophila-containing vacuoles (LCVs) exclude endocytic and lysosomal markers in human macrophages and protozoa. We screened a L. pneumophila mini-Tn10 transposon library for mutants, which fail to inhibit the fusion ... -
Novel cycloheximide derivatives targeting the moonlighting protein Mip exhibit specific antimicrobial activity against Legionella pneumophila
(Frontiers Media Sa, 2015)Macrophage infectivity potentiator (Mip) and Mip-like proteins are virulence factors in a wide range of pathogens including Legionella pneumophila. These proteins belong to the FK506 binding protein (FKBP) family of ... -
Peptidylprolyl cis-trans isomerases of Legionella pneumophila: virulence, moonlighting and novel therapeutic targets
(Portland Press Ltd, 2014)Legionella pneumophila, typically a parasite of free-living protozoa, can also replicate in human alveolar macrophages and lung epithelial cells causing Legionnaires' disease in humans, a severe atypical pneumonia. The ... -
The phenotypes of ATG9, ATG16 and ATG9/16 knock-out mutants imply autophagy-dependent and -independent functions
(Royal Soc, 2015)Macroautophagy is a highly conserved intracellular bulk degradation system of all eukaryotic cells. It is governed by a large number of autophagy proteins (ATGs) and is crucial for many cellular processes. Here, we describe ... -
FKBPs in bacterial infections
(Elsevier Science Bv, 2015)Background: FK506-binding proteins (FKBPs) contain a domain with peptidyl-prolyl-cis/trans-isomerase (PPlase) activity and bind the immunosuppressive drugs FK506 and rapamycin. FKBPs belong to the immunophilin family and ... -
MIPs and aptamers for recognition of proteins in biomimetic sensing
(Mdpi, 2016)Biomimetic binders and catalysts have been generated in order to substitute the biological pendants in separation techniques and bioanalysis. The two major approaches use either "evolution in the test tube" of nucleotides ... -
Novel therapeutic strategies for Clostridium difficile infections
(Taylor & Francis Ltd, 2016)Introduction: In recent years, Clostridium difficile has become the primary cause of antibiotic-associated diarrhea and pseudomembranous colitis, resulting in long and complicated hospital stays that represent a serious ... -
Enzymes as tools in MIP-Sensors
(Mdpi, 2017)Molecularly imprinted polymers (MIPs) have the potential to complement antibodies in bioanalysis, are more stable under harsh conditions, and are potentially cheaper to produce. However, the affinity and especially the ... -
Tyrosine regulates beta-sheet structure formation in amyloid-beta(42): a new clustering algorithm for disordered proteins
(Amer Chemical Soc, 2017)Our recent studies show that the single Tyr residue in the sequence of amyloid-beta(42) (A beta(42)) is reactive toward various ligands, including metals and adenosine trisphospate (see: Coskuner, O. J. Biol. Inorg. Chem. ... -
BMP-2 and BMP-9 binding specificities with ALK-3 in aqueous solution with dynamics
(Elsevier Science Inc, 2017)Signal ligands of the transforming growth factor-beta (TGF-beta) superfamily include the bone morphogenetic proteins (BMPs). BMPs bind to type I and type II serine-threonine kinase receptors and trigger the transphosphorylation ... -
Development of a molecularly imprinted polymer-based electrochemical sensor for tyrosinase
(Scientific & Technical Research Council Turkey-TUBITAK, 2018)For the first time a molecularly imprinted polymer (MIP)-based sensor for tyrosinase is described. This sensor is based on the electropolymerization of scopoletin or o-phenylenediamine in the presence of tyrosinase from ... -
Insights into the molecular mechanisms of Alzheimer's and Parkinson's diseases with molecular simulations: understanding the roles of artificial and pathological missense mutations in intrinsically disordered proteins related to pathology
(Mdpi, 2018)Amyloid-beta and alpha-synuclein are intrinsically disordered proteins (IDPs), which are at the center of Alzheimer's and Parkinson's disease pathologies, respectively. These IDPs are extremely flexible and do not adopt ... -
Molecular LEGO by domain-imprinting of cytochrome P450 BM3
(Elsevier Science Bv, 2018)Hypothesis: Electrosynthesis of the MIP nano-film after binding of the separated domains or holocytochrome BM3 via an engineered anchor should result in domain-specific cavities in the polymer layer. Experiments: Both the ... -
