PRFA, TRANSCRIPTIONAL REGULATOR IN LISTERIA 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)]
About this Structure
2BEO is a [Single protein] structure of sequence from [Listeria monocytogenes] with CL, GLN, PG4 and ACM as [ligands]. Structure known Active Site: AC1. Full crystallographic information is available from [OCA].
Reference
The mutation G145S in PrfA, a key virulence regulator of Listeria monocytogenes, increases DNA-binding affinity by stabilizing the HTH motif., Eiting M, Hageluken G, Schubert WD, Heinz DW, Mol Microbiol. 2005 Apr;56(2):433-46. PMID:15813735
