in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Unknown |
| Product | PPE family protein PPE46 |
| Comments | Rv3018c, (MTV012.32c), len: 434 aa. PPE46, Member of PPE family but lacks Gly, Ala rich repeats at C-terminal domain, closest to MTCY261.19. See citation below. Also very similar to following ORF MTV012.35c. Nearly identical in parts to Mycobacterium tuberculosis protein erroneously described as dihydrofolate reductase (X59271|MTFOLA_1) P31500|DYR_MYCTU (214 aa), FASTA scores: opt: 972, E(): 4.4e-42, (80.0% identity in 195 aa overlap); and Z97559|MTCY261_19 from Mycobacterium tuberculosis cosmid (473 aa), FASTA scores: opt: 806, E(): 0; (38.8% identity in 479 aa overlap); and O53268|MTV012.35c from Mycobacterium tuberculosis (358 aa), FASTA scores: opt: 1714, E(): 3.3e-79, (78.3% identity in 355 aa overlap). |
| Functional category | Pe/ppe |
| 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).
