K. Lesova et al., OR-1 - A mixture of esters of glyceric acid produced by Penicillium funiculosum and its antitrypsin activity, FOL MICROB, 46(1), 2001, pp. 21-23
A mixture of related metabolites (denoted OR-1) was isolated from the ferme
ntation broth of Penicillium funiculosum together with mitorubrinic acid. S
tructurally OR-1 is glyceric acid esterified with C-14-C-18 fatty acids. St
eady-state studies revealed that OR-1 behaved like an uncompetitive trypsin
inhibitor with K-i 17.6 mu mol/L.
