UniProt functional annotation for Q8KGE0



	UniProt functional annotation for Q8KGE0

UniProt code: Q8KGE0.

Organism: Chlorobaculum tepidum (strain ATCC 49652 / DSM 12025 / NBRC 103806 / TLS) (Chlorobium tepidum).

Taxonomy: Bacteria; Chlorobi; Chlorobia; Chlorobiales; Chlorobiaceae; Chlorobaculum.

Function: Involved in the biosynthesis of the major light-harvesting pigment bacteriochlorophyll c (BChlc), which confers a significant competitive advantage to green sulfur bacteria living at limiting red and near-infrared light intensities (PubMed:15090495). Catalyzes the methylation at the C-20 position of the cyclic tetrapyrrole chlorin of bacteriochlorophyll d (BChld) to produce bacteriochlorophyll c (BChlc) using S-adenosylmethionine (SAM) as a methyl source (PubMed:15090495, PubMed:16797589). {ECO:0000269|PubMed:15090495, ECO:0000269|PubMed:16797589}.

Catalytic activity: Reaction=a bacteriochlorophyllide d + S-adenosyl-L-methionine = a bacteriochlorophyllide c + H(+) + S-adenosyl-L-homocysteine; Xref=Rhea:RHEA:49180, ChEBI:CHEBI:15378, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789, ChEBI:CHEBI:90955, ChEBI:CHEBI:90965; EC=2.1.1.333; Evidence={ECO:0000305|PubMed:15090495, ECO:0000305|PubMed:16797589};

Pathway: Porphyrin-containing compound metabolism; bacteriochlorophyll biosynthesis (light-independent). {ECO:0000305|PubMed:15090495}.

Subunit: Homodimer. {ECO:0000269|PubMed:16797589}.

Disruption phenotype: Cells lacking this gene produce only bacteriochlorophyll d (BChld). {ECO:0000269|PubMed:15090495}.

Similarity: Belongs to the class I-like SAM-binding methyltransferase superfamily. Cation-independent O-methyltransferase family. {ECO:0000255|PROSITE-ProRule:PRU01020}.
