Gene Rv2677c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in heme and porphyrin biosynthesis (at the penultimate step). Catalyzes the 6-electron oxidation of protoporphyrinogen IX to form protoporphyrin IX [catalytic activity: protoporphyrinogen-IX + O(2) = protoporphyrin-IX + H(2)O(2)]. |
| Product | Probable protoporphyrinogen oxidase HemY (protoporphyrinogen-IX oxidase) (protoporphyrinogenase) (PPO) |
| Comments | Rv2677c, (MT2751, MTV010.01c), len: 452 aa. Probable hemY, protoporphyrinogen oxidase, equivalent to Q50008|PPOX_MYCLE|HEMY|ML1044 protoporphyrinogen oxidase from Mycobacterium leprae (451 aa), FASTA scores: opt: 2211, E(): 8.8e-118, (75.4% identity in 455 aa overlap). Also similar to others e.g. Q9RV99|DR1130 from Deinococcus radiodurans (462 aa), FASTA scores: opt: 523, E(): 2.7e-22, (29.8% identity in 453 aa overlap); O32434|PPOX_PROFR|HEMY from Propionibacterium freudenreichii shermanii (527 aa), FASTA scores: opt: 344, E(): 4e-12, (32.1% identity in 495 aa overlap); P32397|PPOX_BACSU|HEMY|HEMG from Bacillus subtilis (470 aa), FASTA scores: opt: 305, E(): 5.9e-10, (26.8% identity in 463 aa overlap); etc. Belongs to the protoporphyrinogen oxidase family. Cofactor: contains one FAD per homodimer. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified by mass spectrometry in whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (See de Souza et al., 2011). |
| Mutant | Essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
