Desmosine and isodesmosine as cross‐links in the hinge‐ligament protein of bivalves
1. Desmosine and isodesmosine were detected in an invertebrate molluscan species, i.e. in an insoluble protein in the hinge ligament of a bivalve species, Sakhalin surf clam ( Pseudocardium sachalinensis , in family Mactridae). The protein is rich in glycine and methionine S ‐oxide but devoid of hyd...

| Summary: | 1. Desmosine and isodesmosine were detected in an invertebrate molluscan species, i.e. in an insoluble protein in the hinge ligament of a bivalve species, Sakhalin surf clam ( Pseudocardium sachalinensis , in family Mactridae). The protein is rich in glycine and methionine S ‐oxide but devoid of hydroxyproline and hydroxylysine. 2. 3,3′‐Methylenebistyrosine was also detected in the HCl hydrolysate of the hinge‐ligament protein, but it was found to be an artefact produced from tyrosine and formaldehyde derived from methionine S ‐oxide during the HCl hydrolysis of the protein. |
