Abstract: | Allantoinase and allantoicase are known to form a complex in amphibian liver. In this study, a new type of allantoinase that did not form a complex with allantoicase was found in the amphibian liver. Purified enzyme had a molecular mass of about 44 kDa both in SDS-PAGE and gel-filtrations. The enzyme cross-reacted with anti-sardine allantoinase polyclonal antibody, and it weakly cross-reacted with anti-bullfrog allantoinase polyclonal antibody. |
