3.4.23.26

Accepted name:

rhodotorulapepsin

Reaction:

Specificity similar to that of pepsin A. Cleaves Z-Lys┼Ala-Ala-Ala and activates trypsinogen

Other name(s):

Rhodotorula aspartic proteinase; Cladosporium acid protease; Cladosporium acid proteinase; Paecilomyces proteinase; Cladosporium aspartic proteinase; Paecilomyces proteinase; Rhodotorula glutinis aspartic proteinase; Rhodotorula glutinis acid proteinase; Rhodotorula glutinis aspartic proteinase II; Rhodotorula acid proteinase

Comments:

From the imperfect yeast Rhodotorula glutinis. Somewhat similar enzymes have been isolated from the imperfect yeast-like organism Cladosporium sp. [4,6] and the imperfect fungus Paecilomyces varioti [1,2].
