HHsearch alignment for GI: 254780827 and conserved domain: cd02032

>cd02032 Bchl_like This family of proteins contains bchL and chlL. Protochlorophyllide reductase catalyzes the reductive formation of chlorophyllide from protochlorophyllide during biosynthesis of chlorophylls and bacteriochlorophylls. Three genes, bchL, bchN and bchB, are involved in light-independent protochlorophyllide reduction in bacteriochlorophyll biosynthesis. In cyanobacteria, algae, and gymnosperms, three similar genes, chlL, chlN and chlB are involved in protochlorophyllide reduction during chlorophylls biosynthesis. BchL/chlL, bchN/chlN and bchB/chlB exhibit significant sequence similarity to the nifH, nifD and nifK subunits of nitrogenase, respectively. Nitrogenase catalyzes the reductive formation of ammonia from dinitrogen.
