Hydrolase, haloacid dehalogenase-like family.

Nucleotidyltransferase family protein; Catalyzes the formation of UDP-N-acetylmuramate (UDP-MurNAc), a crucial precursor of the bacterial peptidoglycan cell wall, from UTP and MurNAc-alpha-1P. Is involved in peptidoglycan recycling as part of a cell wall recycling pathway that bypasses de novo biosynthesis of the peptidoglycan precursor UDP-MurNAc. Plays a role in intrinsic resistance to fosfomycin, which targets the de novo synthesis of UDP-MurNAc. Is not able to use GlcNAc-alpha-1P and GalNAc-alpha-1P as substrates. Cannot accept other nucleotide triphosphates (ATP, CTP, TTP, or GTP) [...]

Conserved protein of unknown function; Sugar kinase that catalyzes the ATP-dependent phosphorylation of N-acetylmuramate (MurNAc) and N-acetylglucosamine (GlcNAc) at its C1 hydroxyl group, leading to MurNAc alpha-1P and GlcNAc alpha-1P, respectively. Is involved in peptidoglycan recycling as part of a cell wall recycling pathway that bypasses de novo biosynthesis of the peptidoglycan precursor UDP-MurNAc. Plays a role in intrinsic resistance to fosfomycin, which targets the de novo synthesis of UDP- MurNAc. Is also able to use N-acetylgalactosamine (GalNAc) as a substrate, but not N-ac [...]

Phosphoglycolate phosphatase 2; Specifically catalyzes the dephosphorylation of N- acetylmuramate 6-phosphate (MurNAc-6P) to MurNac. Is involved in peptidoglycan recycling as part of a cell wall recycling pathway that bypasses de novo biosynthesis of the peptidoglycan precursor UDP- MurNAc. Plays a role in intrinsic resistance to fosfomycin, which targets the de novo synthesis of UDP-MurNAc. Shows a very low activity on GlcNAc-6P, and neither alpha-1-phosphorylated MurNAc, GlcNAc, or glucose nor glucosamine-6P or glucose-6P can be used as a substrate. Belongs to the HAD-like hydrolase [...]

Anhydro-N-acetylmuramic acid kinase; Catalyzes the specific phosphorylation of 1,6-anhydro-N- acetylmuramic acid (anhMurNAc) with the simultaneous cleavage of the 1,6-anhydro ring, generating MurNAc-6-P (By similarity). Is required for the utilization of anhMurNAc either imported from the medium or derived from its own cell wall murein, and thus plays a role in cell wall recycling. Contributes to intrinsic fosfomycin resistance in P.putida.

ATP phosphoribosyltransferase regulatory subunit; Required for the first step of histidine biosynthesis. May allow the feedback regulation of ATP phosphoribosyltransferase activity by histidine.

N-acetyl glucosamine-1-phosphate uridyltransferase/glucosamine-1-phosphate acetyl transferase; Catalyzes the last two sequential reactions in the de novo biosynthetic pathway for UDP-N-acetylglucosamine (UDP-GlcNAc). The C- terminal domain catalyzes the transfer of acetyl group from acetyl coenzyme A to glucosamine-1-phosphate (GlcN-1-P) to produce N- acetylglucosamine-1-phosphate (GlcNAc-1-P), which is converted into UDP-GlcNAc by the transfer of uridine 5-monophosphate (from uridine 5- triphosphate), a reaction catalyzed by the N-terminal domain. In the C-terminal section; belongs to [...]

Imidazole glycerol phosphate synthase subunit HisF; IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The HisF subunit catalyzes the cyclization activity that produces IGP and AICAR from PRFAR using the ammonia provided by the HisH subunit.

Imidazole glycerol phosphate synthase subunit HisH; IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The HisH subunit catalyzes the hydrolysis of glutamine to glutamate and ammonia as part of the synthesis of IGP and AICAR. The resulting ammonia molecule is channeled to the active site of HisF.
