An aldehyde oxidase exhibiting high activity on glyoxal was purified to an electrophoretically homogenous state from Pseudomonas sp. AIU 362, which was isolated from a soil sample using a methoxyethanol medium. The enzyme oxidized not only glyoxal but also short-chain aliphatic aldehydes and aromatic aldehydes. Thus, this enzyme was classified into the aldehyde oxidase (ALOD) group. However, it was composed of four identical subunits with a molecular mass of 27 kDa, whereas other microbial ALODs were composed of three hetero subunits, and ALODs from plant and animals were composed of two identical subunits. The NH₂-terminal sequence also showed no similarity to that of other ALODs. These results indicate that ALOD from Pseudomonas sp. AIU 362 is a new aldehyde oxidase. This ALOD was induced by 2-methoxyethanol, methanol or isopropanol.
