Arabidopsis lysin motif/F‐box‐containing protein InLYP1 fine‐tunes glycine metabolism by degrading glycine decarboxylase GLDP2

H-Protein of the Glycine Decarboxylase Multienzyme Complex : Complementary DNA Encoding the Protein from Arabidopsis thaliana.

T-protein of glycine decarboxylase from Solanum tuberosum.

The Gly decarboxylase multienzyme complex (Gly cleavage system, EC 2.1.2.10) catalyzes the conversion of Gly into COz, NH3, and 5,10-methylene-tetrahydrofolate, reducing NAD+ to NADH. The enzyme has been isolated from animals, plants, and bacteria-in animals and plants it occurs exclusively in the mitochondrial matrix, and in photosynthetic tissue it can be found in very large amounts (Bourguig...

P-protein of glycine decarboxylase from Flaveria pringlei.

GDC is the key enzyme of Gly catabolism in bacteria, animals, and plants. In plants this mitochondrial multienzyme complex is involved in the photorespiratory carbon oxidation cycle. Together with Ser hydroxymethyltransferase, it catalyzes the conversion of two molecules of Gly into Ser, COz, and NH3, accompanied by the reduction of NAD+ to NADH (Sarojini and Oliver, 1983). The enzyme complex c...

The glycine decarboxylase system: a fascinating complex.

The mitochondrial glycine decarboxylase multienzyme system, connected to serine hydroxymethyltransferase through a soluble pool of tetrahydrofolate, consists of four different component enzymes, the P-, H-, T- and L-proteins. In a multi-step reaction, it catalyses the rapid destruction of glycine molecules flooding out of the peroxisomes during the course of photorespiration. In green leaves, t...
