Putative hydrolase-oxidase.

Putative solute/DNA competence effector; RNA chaperone with significant RNA binding, RNA strand exchange and RNA duplexing activities. May regulate ProP activity through an RNA-based, post-transcriptional mechanism. Belongs to the ProQ family.

Hypothetical protein; Globally modulates RNA abundance by binding to RNase E (Rne) and regulating its endonucleolytic activity. Can modulate Rne action in a substrate-dependent manner by altering the composition of the degradosome.

Lipopolysaccharide export system protein LptC; Involved in the assembly of lipopolysaccharide (LPS). Required for the translocation of LPS from the inner membrane to the outer membrane. Facilitates the transfer of LPS from the inner membrane to the periplasmic protein LptA. Could be a docking site for LptA. Belongs to the LptC family.

Hypothetical protein; Belongs to the UPF0352 family.

Replication initiation regulator SeqA; Negative regulator of replication initiation, which contributes to regulation of DNA replication and ensures that replication initiation occurs exactly once per chromosome per cell cycle. Binds to pairs of hemimethylated GATC sequences in the oriC region, thus preventing assembly of replication proteins and re- initiation at newly replicated origins. Repression is relieved when the region becomes fully methylated.

Transcriptional repressor for methionine biosynthesis; This regulatory protein, when combined with SAM (S- adenosylmethionine) represses the expression of the methionine regulon and of enzymes involved in SAM synthesis; Belongs to the MetJ family.

SecY interacting protein Syd; Interacts with the SecY protein in vivo. May bind preferentially to an uncomplexed state of SecY, thus functioning either as a chelating agent for excess SecY in the cell or as a regulatory factor that negatively controls the translocase function. Belongs to the Syd family.

Fatty acid metabolism regulator; Multifunctional regulator of fatty acid metabolism.
