Dethiobiotin synthetase: Difference between revisions

Latest revision as of 12:24, 5 June 2019

Dethiobiotin synthetase (DTBS) or ATP-depenent dethiobiotin synthetase catalyzes the first ring closure in the biotin synthesis. The reaction transforms 7,8-diaminononanoate (DAN), ATP and CO2 to dethiobiotin (DTB), ADP and phosphate.^[1]
