The functional differences, as well as differences in three-dimensional structures, between two different enzymes from E. coli result directly from their different: affinity for ATP amino acid sequences secondary structure roles in metabolism

The functional differences, as well as differences in three-dimensional structures, between two different enzymes from E. coli result directly from their different Amino acid Sequence.

Explanation:

Amino acid Sequence in a polypeptide chain is involved in determine the shape and function of a protein. Different enzymes would have different amino acid sequences in the polypeptide chain. The specific sequence of amino acids in an enzyme come from a particular gene on DNA.
