X-ray structure of glyceraldehyde-3-phosphate dehydrogenase from Bacillus stearothermophilus. The N-terminal domain (light blue, residues 1-146) binds NAD+ (drawn in stick form with C green, N blue, O red, and P magenta) near the C-terminal ends of its parallel β strands, and the C-terminal domain (orange, residues 148-333) binds glyceraldehyde-3-phosphate (not shown). Click on the Show button to highlight the Rossmann fold portion of the N-terminal domain with its β sheet green and its remaining segments red.
