Acetylene Inhibition of Azotobacter vinelandii Hydrogenase: Acetylene Binds Tightly to the Large Subunit

Creator:

Sun, Jin-Hua, Hyman, Michael R., and Arp, Daniel J.

Abstract:

Acetylene is a slow-binding inhibitor of the Ni- and Fe-containing dimeric hydrogenase isolated from Azotobacter vinelandii. Acetylene was released from hydrogenase during the recovery from inhibition. This indicates that no transformation of acetylene to another compound occurred as a result of the interaction with hydrogenase. However, the release of C2H2...
