Hyper-adhesion in desmosomes: its regulation in wound healing and possible relationship to cadherin crystal structure
The resistance of tissues to physical stress is dependent upon strong cell-cell adhesion in which desmosomes play a crucial role. We propose that desmosomes fulfil this function by adopting a moreExpand
Molecular Mechanisms of Primary Resistance to Flucytosine in Candida albicans
ABSTRACT Primary resistance in Candida albicans to flucytosine (5-FC) was investigated in 25 strains by identifying and sequencing the genes FCA1, FUR1, FCY21, and FCY22, which code for cytosineExpand
Protein tyrosine phosphatase TbPTP1: a molecular switch controlling life cycle differentiation in trypanosomes
Differentiation in African trypanosomes (Trypanosoma brucei) entails passage between a mammalian host, where parasites exist as a proliferative slender form or a G0-arrested stumpy form, and theExpand
The TriTryp Phosphatome: analysis of the protein phosphatase catalytic domains
BackgroundThe genomes of the three parasitic protozoa Trypanosoma cruzi, Trypanosoma brucei and Leishmania major are the main subject of this study. These parasites are responsible for devastatingExpand
Protein tyrosine phosphatases: structure–function relationships
Structural analysis of protein tyrosine phosphatases (PTPs) has expanded considerably in the last several years, producing more than 200 structures in this class of enzymes (from 35 differentExpand
Protein tyrosine phosphatase structure–function relationships in regulation and pathogenesis
Protein phosphorylation on tyrosine residues is tightly controlled by protein tyrosine phosphatases (PTPs) at multiple levels: spatio‐temporal expression, subcellular localization andExpand
Molecular structure of the A-tract DNA dodecamer d(CGCAAATTTGCG) complexed with the minor groove binding drug netropsin.
The molecular structure of the complex between the minor groove binding drug netropsin and the dodecamer d(CGCAAATTTGCG) has been solved and refined by X-ray diffraction analysis to an R-factor ofExpand
A new family of phosphoinositide phosphatases in microorganisms: identification and biochemical analysis
BackgroundPhosphoinositide metabolism is essential to membrane dynamics and impinges on many cellular processes, including phagocytosis. Modulation of phosphoinositide metabolism is important forExpand
MptpB, a virulence factor from Mycobacterium tuberculosis, exhibits triple-specificity phosphatase activity.
Bacterial pathogens have developed sophisticated mechanisms of evading the immune system to survive in infected host cells. Central to the pathogenesis of Mycobacterium tuberculosis is the arrest ofExpand
Crystal structures of a low-molecular weight protein tyrosine phosphatase from Saccharomyces cerevisiae and its complex with the substrate p-nitrophenyl phosphate.
Low-molecular weight protein tyrosine phosphatases are virtually ubiquitous, which implies that they have important cellular functions. We present here the 2.2 A resolution X-ray crystallographicExpand
