The ability of Pseudomonas fluorescens TR2 proteinase to hydrolyse cheese peptides was examined. TR2 proteinase hydrolysed peptides of cheese water soluble extract, exhibiting a preference for hydrolysis of small peptides. The main peptide produced by the action of pepsin on alpha(s1)-casein was rapidly degraded as indicated by RP-HPLC chromatography. TR2 proteinase degraded a characteristic group of hydrophobic peptides of cow cheese water soluble extract, and more rapidly a broad "hydrophobic" peak of ewe cheese extract. SDS-Page electrophoresis showed that 2 main peptides of both cow and ewe extracts of about 18 and 14 KDa were not degraded by TR2 proteinase. TR2 proteinase did not exhibit aminopeptidase activity.
