Gene Rv3314c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | The enzymes which catalyze the reversible phosphorylosis of pyrimidine nucleosides are involved in the degradation of these compounds and in their utilization as carbon and energy sources, or in the rescue of pyrimidine BASES for nucleotide synthesis [catalytic activity: thymidine + phosphate = thymine + 2-deoxy-D-ribose 1-phosphate]. |
| Product | Probable thymidine phosphorylase DeoA (tdrpase) (pyrimidine phosphorylase) |
| Comments | Rv3314c, (MTV016.14), len: 427 aa. Probable deoA, thymidine phosporylase, highly similar to many e.g. Q9AK36|DEOA from Streptomyces coelicolor (427 aa), FASTA scores: opt: 1668, E(): 3.2e-90, (62.35% identity in 425 aa overlap); Q9CFM5|PDP from Lactococcus lactis (subsp. lactis) (Streptococcus lactis) (430 aa), FASTA scores: opt: 1031, E(): 5.5e-53, (46.45% identity in 392 aa overlap); P19971|TYPH_HUMAN|ECGF1 from Homo sapiens (Human) (482 aa), FASTA scores: opt: 957, E(): 1.3e-48, (44.45% identity in 441 aa overlap); P07650|TYPH_ECOLI|DEOA|TPP|TTG|B4382 from Escherichia coli strain K12 (440 aa), FASTA scores: opt: 847, E(): 3.2e-42, (41.55% identity in 438 aa overlap); etc. Contains PS00647 Thymidine and pyrimidine-nucleoside phosphorylases signature. Belongs to the thymidine/pyrimidine-nucleoside phosphorylases family. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in the membrane protein fraction and whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate (See de Souza et al., 2011). Translational start site supported by proteomics data (See de Souza et al., 2011) (See Kelkar et al., 2011). |
| Mutant | Non-essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Non-essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Non essential gene by Himar1 transposon mutagenesis in H37Rv and CDC1551 strains (see Sassetti et al., 2003 and Lamichhane et al., 2003). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
