Background

The Glycine decarboxylase complex (GDC) is abundant in mitochondria matrix of C3 leaves and functions in photorespiratory carbon recovery. GDC enzyme can account for up to 50% of matrix protein, and is responsible for the most prominent metabolic activity in the mitochondria of illuminated leaves, photorespiration. GDC is a multienzyme complex composed of four component enzymes, the P-, H-, T-, and L-proteins and is responsible for the conversion of glycine produced in the peroxisome to serine in the mitochondria during photorespiratory cycle. The H-protein plays a key role as a mobile substrate that commutes between the other subunits, allowing its lipoic acid “arm” to visit the active sites of the other three components.
