UniProtKB - Q2Y9R4 (CTAA_NITMU)
Protein
Heme A synthase
Gene
ctaA
Organism
Nitrosospira multiformis (strain ATCC 25196 / NCIMB 11849 / C 71)
Status
Functioni
Catalyzes the conversion of heme O to heme A by two successive hydroxylations of the methyl group at C8. The first hydroxylation forms heme I, the second hydroxylation results in an unstable dihydroxymethyl group, which spontaneously dehydrates, resulting in the formyl group of heme A.

: heme A biosynthesis Pathwayi
This protein is involved in step 1 of the subpathway that synthesizes heme A from heme O.UniRule annotation This subpathway is part of the pathway heme A biosynthesis, which is itself part of Porphyrin-containing compound metabolism.View all proteins of this organism that are known to be involved in the subpathway that synthesizes heme A from heme O, the pathway heme A biosynthesis and in Porphyrin-containing compound metabolism.
