ID 1.1.9.1 DE alcohol dehydrogenase (azurin). AN QHEDH. CA a primary alcohol + 2 oxidized [azurin] = an aldehyde + 2 H(+) + CA 2 reduced [azurin]. CC -!- Occurs in Comamonas and Pseudomonas. CC -!- Does not require an amine activator. CC -!- Oxidizes a wide range of primary and secondary alcohols, and also CC aldehydes and large substrates such as sterols; methanol is not a CC substrate. CC -!- Usually assayed with phenazine methosulfate or ferricyanide. CC -!- Like all other quinoprotein alcohol dehydrogenases it has an 8-bladed CC 'propeller' structure, a calcium ion bound to the PQQ in the active CC site and an unusual disulfide ring structure in close proximity to CC the PQQ. CC -!- Formerly EC 1.1.98.1. DR Q4W6G0, QGDA_PSEPU ; Q46444, QHED_COMTE ; Q8GR64, QHED_PSEPU ; //
