Structure at 1.9 A Resolution of a Quinohemoprotein Alcohol Dehydrogenase from Pseudomonas putida HK5


Overview

The type II quinohemoprotein alcohol dehydrogenase of Pseudomonas putida is a periplasmic enzyme that oxidizes substrate alcohols to the aldehyde and transfers electrons first to pyrroloquinoline quinone (PQQ) and then to an internal heme group. The 1.9 A resolution crystal structure reveals that the enzyme contains a large N-terminal eight-stranded beta propeller domain (approximately 60 kDa) similar to methanol dehydrogenase and a small C-terminal c-type cytochrome domain (approximately 10 kDa) similar to the cytochrome subunit of p-cresol methylhydoxylase. The PQQ is bound near the axis of the propeller domain about 14 A from the heme. A molecule of acetone, the product of the oxidation of isopropanol present during crystallization, appears to be bound in the active site cavity.
