The amino acid sequence of the bovine seminal protein, caltrin, which inhibits calcium transport into spermatozoa, has been determined. The protein contains 47 amino acid residues. Parts of the sequence are identical with that reported for bovine seminal plasmin, a protein possessing antibacterial activity. We believe the proteins are identical and that the previously reported sequence of seminal plasmin is in error.
已确定了牛精液蛋白钙调素的氨基酸序列,该蛋白可抑制钙离子向精子内的转运。该蛋白含有47个氨基酸残基。其部分序列与已报道的具有抗菌活性的牛精液纤溶酶的序列相同。我们认为这两种蛋白是相同的,并且之前报道的精液纤溶酶序列有误。
