title: Separation and partial characterization of three forms of collagenase inhibitor from bovine gingiva.
abstract: Three forms of collagenase inhibitor were isolated; one bound to Con A-Sepharose and the other two did not. The Con A-bound (Mr 38,000) and the two unbound (Mr 50,000 and 22,000) inhibitors contained about 20, 15 and 65% of the total inhibitory activity, respectively. The bound and one of the unbound (Mr 22,000) inhibitors were fairly specific for mammalian collagenase; the other unbound inhibitor was rather non-specific and also inhibited trypsin and thermolysin, but not bacterial collagenase. All the inhibitors were heat stable (90 degrees C, 30 min) and unaffected by 4-aminophenylmercuric acetate, but were inactivated by reduction and alkylation.
