Gene Rv3419c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Hydrolysis of O-sialoglycoproteins; cleaves 31-ARG-|-asp-32 bond in glycophorin A. Does not cleave unglycosylated proteins, desialylated glycoproteins or glycoproteins that are only N-glycosylated. Could be a metalloprotease. |
| Product | Probable O-sialoglycoprotein endopeptidase Gcp (glycoprotease) |
| Comments | Rv3419c, (MTCY78.10), len: 344 aa. Probable gcp, glycoprotease, equivalent to P37969|GCP_MYCLE|GCP|ML0379|U229E|U1620c|B229_C3_246|B1620_C3_226 probable glycoprotease from Mycobacterium leprae (351 aa), FASTA scores: opt: 1898, E(): 2.4e-101, (86.1% identity in 345 aa overlap). Highly similar to others e.g. O86793|GCP_STRCO|GCP|SC6G4.30 from Streptomyces coelicolor (374 aa), FASTA scores: opt: 1282, E(): 4.1e-66, (60.45% identity in 344 aa overlap); Q9WXZ2|TM0145 from Thermotoga maritima (327 aa), FASTA scores: opt: 867, E(): 1.9e-42, (45.4% identity in 337 aa overlap); P05852|GCP_ECOLI|B3064 from Escherichia coli strain K12 (337 aa), FASTA scores: opt: 838, E(): 9e-41, (46.55% identity in 346 aa overlap); etc. Shows some similarity to Q50707|YY21_MYCTU|Rv3421c|MTCY78.08 (33.9% identity in 127 aa overlap). Contains PS01016 Glycoprotease family signature. Belongs to peptidase family M22; also known as the glycoprotease family. Conserved in M. tuberculosis, M. leprae, M. bovis and M. avium paratuberculosis; predicted to be essential for in vivo survival and pathogenicity (See Ribeiro-Guimaraes and Pessolani, 2007). |
| Functional category | Intermediary metabolism and respiration |
| 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). Required for growth in C57BL/6J mouse spleen, by transposon site hybridization (TraSH) in H37Rv (See Sassetti and Rubin, 2003). Required for survival in primary murine macrophages, by transposon site hybridization (TraSH) in H37Rv (See Rengarajan et al., 2005). Non-essential gene for in vitro growth of H37Rv, but essential for in vitro growth on cholesterol; by sequencing of Himar1-based transposon mutagenesis (See Griffin et al., 2011).
