Abstract: Preliminary work using a homogenate of hepatopancrease from Pagurus granosimanus (Stimpson, 1859) appeared to show the presence of the enzymes capable of degrading purines. This work was undertaken to confirm these observations and to detect the enzymes present in the following hypothetical sequence: xanthine --(xanthine oxidase)--> uric acid --(uricase)--> allantoin --(allantoinase)--> allantoic acid --(allantoicase)--> urea --(urease)--> ammonia. Included in this is as search for enzymes that would allow the introduciton into the sequence of adenine and guanine.
