Protein Note

Rv1908c, (MTCY180.10), len: 740 aa. katG, catalase-peroxidase-peroxynitritase T (EC 1.11.1.6) (see citations below), HPI. FASTA results: Q57215 CATALASE-PEROXIDASE from Mycobacterium tuberculosis (740 aa) opt: 5081, E(): 0, (100% identity in 740 aa overlap). Contains peroxidases active site signature (PS00436) and ATP/GTP-binding site motif A (P-loop; PS00017). Cosmid sequence was corrected to agree with a sequencing read from the H37Rv genome. DELETIONS OR DEFECTS IN KATG GENE CAUSE ISONIAZID (INH) RESISTANCE. BELONGS TO THE PEROXIDASE FAMILY. BACTERIAL PEROXIDASE/CATALASE SUBFAMILY. KATG TRANSCRIPTION SEEMS TO BE REGULATED BY FURA|Rv1909c PRODUCT. The catalase-peroxidase activity is associated with the amino-terminal domain but no definite function has been assigned to the carboxy-terminal domain. TBparse score is 0.923.
