Glycine decarboxylation and serine synthesis were investigated to account for photorespiratory CO_2 evolution in higher plants. Glycine decarboxylase in leaf mitochondria was found to split glycine into CO_2, NH_3 and a C_1 unit. Free glyoxylic acid was not involved in this process as an intermediate. Serine synthesis was closely related to decarboxylation of glycine. We inferred that serine is formed from two molecules of glycine by the combined action of glcine decarboxylase and serine hydroxymethyltransferase. Glycine decarboxylation and serine synthesis were stimulated by NAD. PALP and THFA, and were inhibited by detergents, lipase, sonication, mechanical treatment, thyroxine and thiol compounds, suggesting the importance of structural intactness of the mitochondrial membrane system. Glycine decarboxylase was present in intact tissues in quantities consistent with glycolate production during photosynthesis. We concluded that glycine decarboxylase in mitochondria is principally responsible for CO_2 evolution in photorespiration. A control mechanism of photorespiration is discussed based on the stimulation of glycine decarboxylase by NAD and on inhibition by NADH.
