Rabbit muscle D-Glyceraldehyde-3-phosphate dehydrogenase: Half-of-the-sites reactivity of the enzyme modified at arginine residues

Modification of a single arginine residue per subunit of rabbit muscle apo-D-Glyceraldehyde-3-phosphate dehydrogenase does not affect the rate of hydrolysis of p-nitrophenyl acetate catalyzed by the enzyme, but locks the tetramer in a conformation wherein only two active sites are functioning. The m...
