3-hydroxyacyl-[acyl-carrier-protein] dehydratase FabZ; Catalyzes the hydrolysis of UDP-3-O-myristoyl-N- acetylglucosamine to form UDP-3-O-myristoylglucosamine and acetate, the committed step in lipid A biosynthesis; Belongs to the thioester dehydratase family. FabZ subfamily.

UDP-3-O-[3-hydroxymyristoyl] glucosamine N-acyltransferase; Catalyzes the N-acylation of UDP-3-O-acylglucosamine using 3- hydroxyacyl-ACP as the acyl donor. Is involved in the biosynthesis of lipid A, a phosphorylated glycolipid that anchors the lipopolysaccharide to the outer membrane of the cell. Belongs to the transferase hexapeptide repeat family. LpxD subfamily.

Elongation factor P; Involved in peptide bond synthesis. Stimulates efficient translation and peptide-bond synthesis on native or reconstituted 70S ribosomes in vitro. Probably functions indirectly by altering the affinity of the ribosome for aminoacyl-tRNA, thus increasing their reactivity as acceptors for peptidyl transferase.

Orotate phosphoribosyltransferase; Catalyzes the transfer of a ribosyl phosphate group from 5- phosphoribose 1-diphosphate to orotate, leading to the formation of orotidine monophosphate (OMP).

The response regulator proteins are involved in the two-component signal transduction systems to detect and respond to environmental changes. The protein consists of two domains, an N-terminal response regulator receiver domain that is substrate for a histidine protein kinase sensor, and a variable C-terminal effector domain, here a PglZ domain, a member of Alkaline phosphatase clan; Localized in the cytoplasm; Family membership.

UDP-3-O-[3-hydroxymyristoyl] glucosamine N-acyltransferase; LpxD catalyzes the third step of lipid A biosynthesis; LpxD features eight tandem repeats of a [LIV]-G-X(4) hexapeptide, which has been shown to fold as a left-handed parallel beta helix; Localized in the cytoplasm; High confidence in function and specificity.

This protein belongs to the UPF0079 family. This group consists of bacterial proteins, which contain a P-loop. They are probably essential to bacteria as members are found in all genomes so far sequenced and no equivalent genes have been found in the archaea and eukaryotes. These proteins adopt a nucleotide-binding fold with a four-stranded parallel beta-sheet flanked by antiparallel beta-strands on each side. The topology of the beta-sheet is unique among P-loop proteins and has features of different families of enzymes. ADP has been shown to bind to the P-loop in the presence of Mg2+ [...]

Deoxyguanosine kinase plays an essential role in generating the deoxyribonucleotide precursors, dGTP and dATP, for DNA metabolism. Localized in the cytoplasm; High confidence in function and specificity.
