Our laboratories have previously measured the capacity for collagenase production by normal and immobilized rabbit periarticular connective tissues (PCT), i.e., anterior cruciate ligaments (ACL), medial collateral ligament (MCL) and patellar tendon (

The amount of anti-collagenase in the root has been reported in a group 18 to 35 years of age. Healthy roots had more than the diseased; and apical more than the cervical. The purpose of the present study is to determine the effect of age on these va

Under specific conditions cysteine inhibits collagenase (Clostridiopeptidase A and B (EC 3.4.4.19)) irreversibly. Neither collagenase A or B contains cysteinyl or cystinyl residues, so that the inhibition cannot proceed either by disulfide reduction,

The effect of pepsin solubilization on the platelet aggregating activity of type I collagen and type III collagen was examined. Pepsin-digested type I collagen was unable to initiate platelet aggregation in either soluble form or as pre-formed fibril

Three collagenases from Clostridium histolyticum, designated C1, C2, and C3, with apparent molecular weights of 96 000, 92 000, and 76 000 were purified. Peptide maps of the enzymes prepared by digestion with Staphylococcus aureus V-8 protease were f

The interaction between platelets and collagen, which marks the initiation of hemostasis, was examined as a function of the conformation and the multimerization of soluble guinea pig skin collagen. Both the rate and extent of collagen multimerization

The previous paper (1) presented some correlations between collagen multimer formation and platelet aggregation. The present study investigates the effect of chemical or enzymic modification upon its melting temperature and rate of multimerization, a

Bovine eyes were dissected and separate pools of lens, lens capsule, cornea and vitreous were extracted in guanidine, subjected to ultrafiltration, and examined for their effects on collagenolytic activity. Although lens extract was not inhibitory, t

The purified collagenase from tadpole (Rana catesbiana) back skin was studied with respect to its activation energy using soluble and fibrillar type I collagen, as well as a synthetic peptide substrate, DNPProGlnGlyIleAlaGlyGln

In cultures of tadpole tissues which produce collagenase, an activator of procollagenase appears in the medium simultaneously with active enzyme and a precursor product relationship exists between the amounts of zymogen and enzyme liberated into the
