DNA-directed RNA polymerase alpha chain; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.

Lysine export transcriptional regulatory protein LysG; Probable transcriptional regulator of lysE. Identified by similarity to protein SP: P94632 (Corynebacterium glutamicum); Belongs to the LysR transcriptional regulatory family.

GntR-family transcriptional regulator; Identified by match to protein family PF00392. This family of regulatory proteins consists of the N-terminal HTH region of GntR-like bacterial transcription factors. At the C-terminus there is usually an effector-binding/oligomerisation domain. The GntR-like proteins can be divided into six sub-families: MocR, YtrR, FadR, AraR, HutC and PlmA. Many of these proteins have been shown experimentally to be autoregulatory, enabling the prediction of operator sites and the discovery of cis/trans relationships.

Putative NAD-dependent deacetylase; Identified by match to PF02146: Sir2 family. Sir2 proteins, also known as sirtuins, are found in all eukaryotes and many archaea and prokaryotes and have been shown to regulate gene silencing, DNA repair, metabolic enzymes, and life span. Function: modulate the activities of several enzymes which are inactive in their acetylated form. Catalytic activity: NAD+ + an acetylprotein = nicotinamide + O-acetyl-ADP-ribose + a protein.

AraC-family transcriptional regulator; Identified by match to protein domain PF00165: bacterial regulatory helix-turn-helix proteins, AraC family.

Iron-siderophore ABC transporter, substrate-binding protein; TCDB: ATP-binding cassette (ABC) superfamily, iron chelate uptake transporter (FeCT) family (TC 3.A.1.14.z). ABCISSE: ABC transporter, binding protein (BP), ISVH-family (iron siderophores, vitamin B12 and hemin).
