Abstract
- Cysteic and cysteine sulphinate decarboxylase activities have been determined in rat retina, brain, liver, kidney, lung and spleen during postnatal growth. 2) The two enzymic activities increase as function of age in retina, brain and liver. 3) In contrast the cysteic and cysteine sulphinate decarboxylase activities decrease with age in kidney, lung and spleen. 4) The rate of decarboxylation of cysteine sulphinate is higher than cysteic acid and the ratio of the two decarboxylating activities for each tissue is constant; this uniformity may exclude the existence of two separate enzymes.
摘要
- 已测定了出生后生长期间大鼠视网膜、脑、肝、肾、肺和脾中的半胱磺酸和半胱氨酸亚磺酸脱羧酶活性。2) 在视网膜、脑和肝中，这两种酶活性随年龄增长而增加。3) 相比之下，在肾、肺和脾中，半胱磺酸和半胱氨酸亚磺酸脱羧酶活性随年龄增长而降低。4) 半胱氨酸亚磺酸的脱羧速率高于半胱磺酸，并且每个组织中两种脱羧活性的比率是恒定的；这种一致性可能排除了两种独立酶的存在。
