the labeling occurred exclusively at the allosteric specificity site as evidenced by 1 ) total inhibition of the labeling by dgtp and dttp , 2 ) normal photoincorporation of [ 32p ] datp by mutant protein m1 molecules that lack a functional activity site , and 3 ) coidentity of one-dimensional peptide maps of protein m1 labeled with either [ 32p ] datp or [ 32p ] dttp .
