Abstract
  1. A lactate dehydrogenase isoenzyme present in human spermatozoa and semen was isolated and characterized biochemically in term of its pH for optimum activity and by means of K(m) values for lactate, NAD(+) and NAD analogues. The results were compared with those obtained with the human heart-type and the liver-type lactate dehydrogenase isoenzymes. 2. The enzyme was characterized by its resistance to digestion with different proteolytic enzymes. The time for 50% digestion in terms of residual dehydrogenase activity was compared with times obtained for the H(4)- and M(4)-types.
摘要
  1. 从人类精子和精液中分离出一种乳酸脱氢酶同工酶,并根据其最适活性的pH值以及乳酸、NAD⁺和NAD类似物的米氏常数(Km值)进行了生化特性鉴定。将结果与人类心脏型和肝脏型乳酸脱氢酶同工酶的结果进行了比较。2. 该酶的特点是对不同的蛋白水解酶具有抗性。根据残留脱氢酶活性比较了50%消化所需的时间与H₄型和M₄型的时间。
