  The present invention provides a method of producing optically active amino acids from 5-substituted hydantoin by isolating a hydantoinase gene and an N-carbamyl-L-amino acid hydrolase gene involved in an ability to convert 5-substituted hydantoin or N-carbamylamino acid into optically active amino acids from a microorganism of the genus Microbacterium having the above ability and by improving gene amplification and transcriptional and translational activities thereby preparing a recombinant wherein the amount of the desired enzymes produced is increased. The hydantoinase gene is, for example, a DNA encoding for a protein having a hydantoinase activity, which has the nucleotide sequence set forth in SEQ ID NO:1 in the Sequence. The N-carbamyl-L-amino acid hydrolase gene is, for example, a DNA encoding for a protein having an N-carbamyl-L-amino acid hydrolase activity, which has the nucleotide sequence set forth in SEQ ID NO:3 in the Sequence.

  本发明提供了一种从5-取代的海因中生产光学活性氨基酸的方法，其方法是从具有上述能力的微细菌属微生物中分离出一种参与将5-取代的海因或N-氨甲酰-L-氨基酸转化为光学活性氨基酸的能力的海因酶基因和N-氨甲酰-L-氨基酸水解酶基因，并通过改进基因扩增和转录及翻译活性从而制备出一种重组体，在该重组体中所产生的所需酶的量有所增加。例如， hydantoinase 基因是编码具有 hydantoinase 活性的蛋白质的 DNA，其核苷酸序列见序列 SEQ ID NO:1 所列。例如，N-氨基甲酰-L-氨基酸水解酶基因是编码具有 N-氨基甲酰-L-氨基酸水解酶活性的蛋白质的 DNA，其核苷酸序列见序列 SEQ ID NO:3。
