>TIGR01202 bchC Chlorophyll synthesis pathway, bchC; InterPro: IPR005903 Some prokaryotes, such as the purple and green sulphur bacteria, gain energy from a mode of photosynthesis that does not generate oxygen, and is inhibited by its presence , . These organisms do not include chlorophylls in their photosynthetic pigments, but instead use closely related molecules known as bacteriochlorophylls. Like chlorophylls, bacteriochlorophylls are tetrapyroles with a five-membered ring structure, differing in the side chains and hydration state of the ring structure. These alterations in structure determine what light wavelengths can be harvested by the organism . Bacteriochlorophyll a is a photosynthetic pigment found in many of the purple bacteria. It is synthesised from protoporphyrin IX in a series of reactions including magnesium-chelation, methyl transfer, ring formation, vinyl-group reduction protochlorophyllide reduction, and finally phytol addition . This entry represents 2-desacetyl-2-hydroxyethyl bacteriochlorophyllide a dehydrogenase, the enzyme catalysing the penultimate step in light-independent bacteriochlorophyll a biosynthesis .; GO: 0016491 oxidoreductase activity, 0030494 bacteriochlorophyll biosynthetic process.
