Enterococcus faecalis BM4518 is resistant to vancomycin by synthesis of peptidoglycan precursors ending in D-alanyl-D-serine . In the chromosomal vanG locus , transcription of the resistance genes from the PYG resistance promoter is inducible and , upstream from these genes , there is an unusual three-component regulat... | Various modes of gene regulation coexist in cells . One corresponds to the “switch on/ off” mechanism in which the regulator induces the promoter to a defined level . In another mechanism , the regulator activates the promoter to various levels according to the intensity or the nature of an input signal . In this study... | [

Catalytic loop motions facilitate substrate recognition and binding in many enzymes . While these motions appear to be highly flexible , their functional significance suggests that structure-encoded preferences may play a role in selecting particular mechanisms of motions . We performed an extensive study on a set of e... | Protein loops have critical roles in ligand binding and catalysis . An unresolved issue in this context is the extent to which the intrinsic dynamics of proteins predispose loops to perform their molecular function . In this work , we ( i ) critically examine the structural changes undergone by functional/catalytic loo... | [

Candida albicans is a common commensal in the human gut but in predisposed patients it can become an important human fungal pathogen . As a commensal , C . albicans adapts to low-oxygen conditions and represses its hyphal development by the transcription factor Efg1 , which under normoxia activates filamentation . The ... | Candida albicans is an important cause of human disease that occurs if the fungus proliferates strongly on skin surfaces or in several internal organs causing superficial and systemic mycosis . Remarkably , at low cell numbers , C . albicans is also a normal inhabitant of mucosal surfaces and the gut and it is believed... | [

Mother-to-infant transmission ( MTIT ) of HIV is a serious global health concern , with over 300 , 000 children newly infected in 2011 .
