PRFA-G145S, A CONSTITUTIVE ACTIVE MUTANT OF THE TRANSCRIPTIONAL REGULATOR IN L.MONOCYTOGENES
Overview
Listeria monocytogenes, a Gram-positive, facultative intracellular human, pathogen, causes systemic infections with high mortality rate. The, majority of the known pathogenicity factors of L. monocytogenes is, regulated by a single transcription factor, PrfA. Hyperhaemolytic, laboratory strains of L. monocytogenes express the constitutively active, mutant PrfA(G145S) inducing virulence gene overexpression independent of, environmental conditions. PrfA belongs to the Crp/Fnr family of, transcription factors generally activated by a small effector, such as, cAMP or O(2). We present the crystal structures of wild-type PrfA, the, first Gram-positive member of the Crp/Fnr family, and of the, constitutively active mutant PrfA(G145S). Cap (Crp) has previously been, described exclusively in the ... [(full description)]
