HHsearch alignment for GI: 254780487 and conserved domain: cd02033
>cd02033 BchX Chlorophyllide reductase converts chlorophylls into bacteriochlorophylls by reducing the chlorin B-ring. This family contains the X subunit of this three-subunit enzyme. Sequence and structure similarity between bchX, protochlorophyllide reductase L subunit (bchL and chlL) and nitrogenase Fe protein (nifH gene) suggest their functional similarity. Members of the BchX family serve as the unique electron donors to their respective catalytic subunits (bchN-bchB, bchY-bchZ and nitrogenase component 1). Mechanistically, they hydrolyze ATP and transfer electrons through a Fe4-S4 cluster.
