HHsearch alignment for GI: 254780872 and conserved domain: TIGR02021

>TIGR02021 BchM-ChlM magnesium protoporphyrin O-methyltransferase; InterPro: IPR010251 Chlorophyll and bacteriochlorophyll are essential photosynthetic pigments involved in oxygenic and non-oxygenic photosythesis respectively. They are both synthesised from protoporphyrin IX in complex pathways which share many common steps. The second committed step in both pathways is the methylation of magnesium protoporphyrin IX, catalysed by magnesium protoporphyrin O-methyltransferase with S-adenosyl methionine (SAM) as the methyl donor , , .Sequence alignments suggest that the protein contains the characteristic seven-stranded beta-sheet fold found in other SAM-dependent methyltransferases. This entry represents magnesium protoporphyrin O-methyltransferase from cyanobacteria and plants, where it is known as ChlM, and from other photosynthetic bacteria, where it is known as BchM.; GO: 0046406 magnesium protoporphyrin IX methyltransferase activity, 0015979 photosynthesis, 0015995 chlorophyll biosynthetic process.
