FunctionTransaldolase (TAL) is part of the pentose phosphate pathway. It catalyzes the transformation of sedoheptulose 7-phosphate and glyceraldehyde 3-phosphate to erythrose 4-phosphate and fructose 6-phosphate[1]. See also Lysine-cysteine NOS bonds. DiseaseTAL deficiency influences mitochondrial homeostasis, Ca+2 fluxing and apoptosis[2]. Structural highlightsTAL overall structure is of a (Alpha Helices, Beta Strands , Loops , Turns). The at [3]. Water molecules are shown as red spheres. . 3D Structures of transaldolase |
