General annotation
Gene namehemN
Rv numberRv2388c
FunctionInvolved in porphyrin biosynthesis. Anaerobic transformation of coproporphyrinogen-III into protoporphyrinogen-IX.
ProductProbable oxygen-independent coproporphyrinogen III oxidase HemN (coproporphyrinogenase) (coprogen oxidase)
CommentsRv2388c, (MTCY253.33), len: 375 aa. Probable hemN, oxygen-independent coproporphyrinogen III oxidases, highly similar to many putative oxygen-independent coproporphyrinogen III oxidases e.g. Q9RDD2|SCC77.26 from Streptomyces coelicolor (435 aa), FASTA scores: opt: 1358, E(): 1.5e-76, (56.55% identity in 382 aa overlap); BAB51237|MLR4627 from Rhizobium loti (Mesorhizobium loti) (392 aa), FASTA scores: opt: 696, E(): 1.1e-35, (36.8% identity in 383 aa overlap); Q9KUR0|VC0455 from Vibrio cholerae (391 aa), FASTA scores: opt: 691, 2.2e-35, (32.65% identity in 386 aa overlap); P54304|HEMN_BACSU from Bacillus subtilis (366 aa), FASTA scores: opt: 668 , E(): 5.6e-34; (34.9% identity in 327 aa overlap); etc. Equivalent to AAK46752 from Mycobacterium tuberculosis strain CDC1551 (390 aa) but shorter 375 aa. Belongs to the anaerobic coproporphyrinogen III oxidase family.

Functional categoryintermediary metabolism and respiration

Mutationnon essential gene by Himar1-based 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). Non-essential gene for in vitro growth of H37Rv, by sequencing of Himar1-based transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website
