A cytosolic enzyme is encoded by a gene whose coding sequence includes codons 45–47: 5'-GAA CCT TTT-3', producing mRNA 5'-GAA CCU UUU-3' and amino acids Glu–Pro–Phe. In a mutant, one nucleotide is deleted from the DNA within codon 45, changing the sequence to 5'-GAC CTT TT…-3' from that point onward. No other changes occur in the gene. The enzyme's active site depends on amino acids encoded downstream of codon 45. Which outcome is most likely from this mutation?
