1) 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.

Abstract
1) 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.File in questo prodotto:
