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

Sun, Jin-Hua; Hyman, Michael R.; Arp, Daniel J. (American Chemical Society, 1992)

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 t ...
Carbonyl Sulfide Inhibition of CO Dehydrogenase from Rhodospirillum rubrum

Hyman, Michael R.; Ensign, Scott A.; Arp, Daniel J.; Ludden, Paul W. (American Chemical Society, 1989)

Carbonyl sulfide (COS) has been investigated as a rapid-equilibrium inhibitor of CO oxidation by the CO dehydrogenase purified from Rhodospirillum rubrum. The kinetic evidence suggests that the inhibition by COS is lar ...
Kinetic and Spectroscopic Analysis of the Inactivating Effects of Nitric Oxide on the Individual Components of Azotobacter vinelandii Nitrogenase

Hyman, Michael R.; Seefeldt, Lance C.; Morgan, Vance; Arp, Daniel J.; Mortenson, Leonard E. (American Chemical Society, 1992)

The effects of nitric oxide (NO) on the individual components of Azotobacter vinelandii nitrogenase have been examined by kinetic and spectroscopic methods. Incubation of the Fe protein (Av2) for 1 h with stoichiometri ...
