Abstract
An L-lysine .alpha.-oxidase, that is, a novel L-amino acid oxidase having very high substrate-specificity to L-lysine is produced by culturing a specific microorganism belonging to Trichoderma in a medium.
Claims6
L-lysine .alpha.-oxidase which is an L-amino acid oxidase having an ability to form .alpha.-keto-.epsilon.-aminocaproic acid, ammonia and hydrogen peroxide from L-lysine by oxidative deamination of L-lysine in the presence of water and oxygen as well as having a very low Km value with respect to L-lysine and the high substrate-specificity with respect to L-lysine.
A process for production of L-lysine .alpha.-oxidase which comprises culturing a strain belonging to the genus of Trichoderma having an ability to produce L-lysine .alpha.-oxidase in a medium and isolating L-lysine .alpha.-oxidase from the resulting culture product.
