This entry represents a group of NAD(P)-binding proteins from plants and bacteria, including divinyl reductase (DVR) from higher plants. DVR converts 8-vinyl groups on various chlorophyll intermediates to ethyl groups, which is indispensable for chlorophyll biosynthesis. Interestingly, DVR proteins from different species have diverse and differing substrate preferences [ 1 ].

1. One divinyl reductase reduces the 8-vinyl groups in various intermediates of chlorophyll biosynthesis in a given higher plant species, but the isozyme differs between species. Plant Physiol. 161, 521-34
