Your Input: | |||||
Sros_1722 | Nicotinate phosphoribosyltransferase; Catalyzes the first step in the biosynthesis of NAD from nicotinic acid, the ATP-dependent synthesis of beta-nicotinate D- ribonucleotide from nicotinate and 5-phospho-D-ribose 1-phosphate. Belongs to the NAPRTase family. (428 aa) | ||||
pyrR | Uracil phosphoribosyltransferase; Also displays a weak uracil phosphoribosyltransferase activity which is not physiologically significant. (193 aa) | ||||
hisH | 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. (209 aa) | ||||
hisF | 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. (256 aa) | ||||
Sros_3378 | Hypothetical protein. (121 aa) | ||||
Sros_4306 | KEGG: rsk:RSKD131_2976 hypothetical protein; Belongs to the multicopper oxidase YfiH/RL5 family. (246 aa) | ||||
kptA | Putative RNA 2'-phosphotransferase; Removes the 2'-phosphate from RNA via an intermediate in which the phosphate is ADP-ribosylated by NAD followed by a presumed transesterification to release the RNA and generate ADP-ribose 1''-2''- cyclic phosphate (APPR>P). May function as an ADP-ribosylase. (187 aa) | ||||
trpD-2 | Anthranilate phosphoribosyltransferase; Catalyzes the transfer of the phosphoribosyl group of 5- phosphorylribose-1-pyrophosphate (PRPP) to anthranilate to yield N-(5'- phosphoribosyl)-anthranilate (PRA). (352 aa) | ||||
Sros_6259 | KEGG: mch:Mchl_3109 protein of unknown function DUF152; Belongs to the multicopper oxidase YfiH/RL5 family. (228 aa) | ||||
apt | Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis. (172 aa) | ||||
cobT | Nicotinate-nucleotide--dimethylbenzimidazolephos phoribosyltransferase; Catalyzes the synthesis of alpha-ribazole-5'-phosphate from nicotinate mononucleotide (NAMN) and 5,6-dimethylbenzimidazole (DMB). (382 aa) | ||||
Sros_8450 | Membrane protein-like protein; KEGG: azo:azo2381 dolichyl-phosphate-mannose- protein mannosyltransferase. (506 aa) | ||||
Sros_8654 | Methylthioadenosine phosphorylase; Purine nucleoside phosphorylase involved in purine salvage. (269 aa) | ||||
purF | Amidophosphoribosyltransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine. (478 aa) | ||||
Sros_9176 | KEGG: bha:BH0084 hypoxanthine-guanine phosphoribosyltransferase; Belongs to the purine/pyrimidine phosphoribosyltransferase family. (180 aa) | ||||
upp | Uracil phosphoribosyltransferase; Catalyzes the conversion of uracil and 5-phospho-alpha-D- ribose 1-diphosphate (PRPP) to UMP and diphosphate. (212 aa) | ||||
hisG | ATP phosphoribosyltransferase; Catalyzes the condensation of ATP and 5-phosphoribose 1- diphosphate to form N'-(5'-phosphoribosyl)-ATP (PR-ATP). Has a crucial role in the pathway because the rate of histidine biosynthesis seems to be controlled primarily by regulation of HisG enzymatic activity. Belongs to the ATP phosphoribosyltransferase family. Long subfamily. (281 aa) | ||||
pyrE | 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). (178 aa) | ||||
Sros_1274 | Thymidine phosphorylase; KEGG: ank:AnaeK_0651 pyrimidine-nucleoside phosphorylase. (426 aa) | ||||
Sros_5993 | Membrane protein-like protein; KEGG: aba:Acid345_3975 glycosyl transferase, family 39. (478 aa) | ||||
Sros_1283 | Conserved hypothetical protein; The purine nucleoside phosphorylases catalyze the phosphorolytic breakdown of the N-glycosidic bond in the beta- (deoxy)ribonucleoside molecules, with the formation of the corresponding free purine bases and pentose-1-phosphate. (267 aa) | ||||
trpD | Anthranilate phosphoribosyltransferase; Catalyzes the transfer of the phosphoribosyl group of 5- phosphorylribose-1-pyrophosphate (PRPP) to anthranilate to yield N-(5'- phosphoribosyl)-anthranilate (PRA). (348 aa) |
