General Information

General Information Comment Organism
evolution ZSD1 is a member of the short-chain dehydrogenase/reductase superfamily, SDR, and shares high identities with other plant SDRs involved in secondary metabolism, stress responses and phytosteroid biosynthesis Zingiber zerumbet
metabolism ZSD1 is an alcohol dehydrogenase capable of catalyzing the final step of zerumbone biosynthesis, but ZSD1 is also be involved in other biological processes Zingiber zerumbet
additional information the enzyme contains an active site sequence 155Y-X-X-X-K159, Ser142 completes the Ser-Tyr-Lys triad responsible for the catalysis of ZSD1 Zingiber zerumbet
physiological function ZSD1 is involved in secondary metabolism, stress responses and phytosteroid biosynthesis Zingiber zerumbet
