ATP-Grasp family ATPase; May be a ligase forming an amide bond. Shows ATPase activity. Despite its similarity to the C-terminal synthetase domain of Gss, is not a glutathionylspermidine (Gsp) synthetase. Cannot synthesize Gsp, glutathione (GSH), or GSH intermediates, from GSH and spermidine, cysteine and glutamate, gamma-glutamylcysteine and spermidine, and gamma-glutamylcysteine and glycine. Does not bind to Gsp. Belongs to the glutathionylspermidine synthase preATP-grasp family.

UPF0719 family inner membrane protein.

BamABCDE complex OM biogenesis lipoprotein; Part of the outer membrane protein assembly complex (Bam), which is involved in assembly and insertion of beta-barrel proteins into the outer membrane. Nonessential member of the complex that stabilizes the interaction between the essential proteins BamA and BamD. Efficient substrate folding and insertion into the outer membrane requires all 5 subunits. A lateral gate may open between the first and last strands of the BamA beta-barrel that allows substrate to insert into the outer membrane; comparison of the structures of complete and nearly [...]

Transport channel; Outer membrane channel, which is required for the function of several efflux systems such as AcrAB-TolC, AcrEF-TolC, EmrAB-TolC and MacAB-TolC. These systems are involved in export of antibiotics and other toxic compounds from the cell. TolC is also involved in import of colicin E1 into the cells.

DUF1768 family protein; Catalyzes the hydrolysis of the N-glycosidic bond in the first two intermediates of riboflavin biosynthesis, which are highly reactive metabolites, yielding relatively innocuous products. Thus, can divert a surplus of harmful intermediates into relatively harmless products and pre-empt the damage these intermediates would otherwise do. Helps maintain flavin levels. May act on other substrates in vivo. Has no activity against GTP, nucleoside monophosphates or ADP-ribose. Is Required for swarming motility.

TDP-fucosamine acetyltransferase; Catalyzes the acetylation of dTDP-fucosamine (dTDP-4-amino- 4,6-dideoxy-D-galactose) to dTDP-Fuc4NAc, which is utilized in the biosynthesis of the enterobacterial common antigen (ECA). Belongs to the WecD family.

TDP-Fuc4NAc:lipidIIFuc4NAc transferase; Catalyzes the synthesis of Und-PP-GlcNAc-ManNAcA-Fuc4NAc (Lipid III), the third lipid-linked intermediate involved in ECA synthesis; Belongs to the glycosyltransferase 56 family.

Glutathionylspermidine amidase and glutathionylspermidine synthetase; Catalyzes the formation of an amide bond between glutathione (GSH) and spermidine coupled with hydrolysis of ATP; also catalyzes the opposing reaction, i.e. the hydrolysis of glutathionylspermidine (Gsp) back to glutathione and spermidine. The amidase active site can also hydrolyze Gsp-disulfide (Gsp-S-S-Gsp) to Gsp-SG and Gsp S-thiolated proteins (GspSSPs) to GSH S-thiolated protein (GSSPs). Likely acts synergistically with glutaredoxin to regulate the redox environment of E.coli and defend against oxidative damage. [...]

ADP-ribose pyrophosphatase; Acts on ADP-mannose and ADP-glucose as well as ADP-ribose. Prevents glycogen biosynthesis. The reaction catalyzed by this enzyme is a limiting step of the gluconeogenic process. Belongs to the Nudix hydrolase family. NudF subfamily.
