Gene Rv3608c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in dihydrofolate biosynthesis (at the second step). Catalyzes the formation of the immediate precursor of FOLIC acid. It is implicated in resistance to sulfonamide [catalytic activity: 2-amino-4-hydroxy-6-hydroxymethyl-7,8-dihydropteridine diphosphate + 4-aminobenzoate = pyrophosphate + dihydropteroate]. |
| Product | Dihydropteroate synthase 1 FolP (DHPS 1) (dihydropteroate pyrophosphorylase 1) (dihydropteroate diphosphorylase 1) |
| Comments | Rv3608c, (MTCY07H7B.14), len: 280 aa. Probable folP1, dihydropteroate synthase 1, equivalent to O69530|FOLP (alias Q9S0T0|FOLP and Q9R2U9|FOLP) dihydroneopterin aldolase from Mycobacterium leprae (284 aa), FASTA scores: opt: 1418, E(): 7.2e-77, (76.75% identity in 284 aa overlap). Also highly similar to many e.g. Q9X8H8|SCE9.05 from Streptomyces coelicolor (288 aa), FASTA scores: opt: 953, E(): 2.4e-49, (56.0% identity in 266 aa overlap); Q9A3I0|CC3224 from Caulobacter crescentus (274 aa), FASTA scores: opt: 682, E(): 2.6e-33, (45.5% identity in 268 aa overlap); P73248|DHPS_SYNY3|FOLP|SLR2026 from Synechocystis sp. strain PCC 6803 (289 aa), FASTA scores: opt: 665, E(): 2.7e-32, (44.55% identity in 265 aa overlap); P26282|DHPS_ECOLI|FOLP|B3177 from Escherichia coli strain K12 (282 aa), FASTA scores: opt: 642, E(): 6.1e-31, (41.95% identity in 274 aa overlap); etc. Contains PS00792 Dihydropteroate synthase signature 1, PS00793 Dihydropteroate synthase signature 2. Similar to other species DHPS. |
| Functional category | Intermediary metabolism and respiration |
