... assembly of for- oxymithine by a synthetase lacking all E-domains. The lack of sequence information for the S. nitrosporeus genome impeded the identification of a biosynthetic machinery governing foroxymithine ... to the identification of the second siderophore (data not shown). We therefore assume that either the extraction conditions were inadequate for the iso- la...

... respectively. On the other hand, oxidation of M25L elafin and M63L trappin did not significantly affect their K i for NE (Table 2). We therefore conclude that the oxidant-promoted alteration of the K i of elafin and ... binding of the methionine sulfoxide residue at the S 1 ¢ subsite of the active centers of NE and Pr3. The fact that the S 1 ¢ subsite of Pr3 is si...
