| - | [ | + | [https://www.uniprot.org/uniprot/RPFB_MYCTU RPFB_MYCTU] Factor that stimulates resuscitation of dormant cells. Has peptidoglycan (PG) hydrolytic activity. Active in the pM concentration range. Has little to no effect on actively-growing cells. PG fragments could either directly activate the resuscitation pathway of dormant bacteria or serve as a substrate for endogenous Rpf, resulting in low molecular weight products with resuscitation activity.<ref>PMID:12410821</ref> <ref>PMID:12906837</ref> <ref>PMID:18463693</ref> <ref>PMID:20016836</ref> Reduces lag phase and enhances the growth of quiescent (1 month-old culture) M.tuberculosis; works best between 8 and 128 pM. Increases the number of bacteria that can be recovered from a 3 month-old culture. Stimulates growth of stationary phase M.bovis (a slowly-growing Mycobacterium) as well as M.smegmatis cells (a fast grower). Binds N,N',N''-triacetylchitotriose (tri-NAG). A fragment (residues 194-362) hydrolyzes an artificial lysozyme substrate 4-methylumbelliferyl-beta-D-N,N',N''-triacetylchitotrioside (MUF tri-NAG). By itself has little activity on cell wall, in combination with RipA is active against cell wall extracts from a number of Actinobacteria; this activity is inhibited by PBP1A (ponA1). Sequential gene disruption indicates RpfB and RpfE are higher than RpfD and RpfC in functional hierarchy.<ref>PMID:12410821</ref> <ref>PMID:12906837</ref> <ref>PMID:18463693</ref> <ref>PMID:20016836</ref> |
