Abstract:
:Tritiated sodium borohydride was used to reduce the substrates of triosephosphate isomerase in the presence of the enzyme, and the mixture of the four possible products (D-[1(R)-3H]; D-[1(S)-3H]-; D-[2-3H]-, and L-[2-3H]glycerol 3-phosphate) was analyzed. While enzyme-bound dihydroxyacetone phosphate is reduced completely stereoselectively and at a rate eight imes faster than in free solution, D-glyceraldehyde 3-phosphate is inaccessible to reduction by borohydride when bound to the active site of the enzyme.
