Post‐mortem Degradation of Adenine Nucleotides in Muscle of the Lobster,Homarus americanus

摘要

SUMMARY—Thin‐layer chromatography showed that postmortem degradation of adenine nucleotides in the tail muscle of lobster(Homarus americanus)followed the route: adeno‐sine 5′‐triphosphate (ATP) → adenosine 5′‐diphosphate (ADP) → adenosine S'monophosphate (AMP) → inosine 5′‐mono‐phosphate (IMP) + inosine (Ino) → hypoxanthine (Hx). KCI extracts (0.6M) also degraded ATP by this route. Such extracts contained a weak AMP‐aminohydrolase activity that was activated by ATP, but no adenosine aminohydrolase could be detected. Neither of these aminohydrolases were found in extracts made wit
