L-HYDANTOINASE (DIHYDROPYRIMIDINASE) FROM ARTHROBACTER AURESCENS
Overview
L-Hydantoinase from Arthrobacter aurescens (L-Hyd) is a member of the, dihydropyrimidinases which in turn belong to the cyclic amidases., Dihydropyrimidinases catalyze the reversible hydrolytic ring opening of, dihydropyrimidines as the second step in the catabolism of pyrimidines. In, biotechnology, their hydroloytic activity on five-membered cyclic diamides, (hydantoins) is used in the enantio-specific production of amino acids, from racemic hydantoins. L-Hyd differs from most of the other, dihydropyrimidinases by an L-enantio specificity and by lacking activity, on possible natural substrates such as dihydropyrimidines. In this paper, we describe the three-dimensional structure of L-Hyd which was solved by, molecular replacement using a homology model and subsequently refined to, 2.6 A ... [(full description)]
