An Individual Has a Metabolic Disorder That Is Traced to an Enzyme

Short Answer

An individual has a metabolic disorder that is traced to an enzyme composed of two different subunits, one larger than the other.The patient has an allele of the smaller subunit that produces a protein that is abnormally large, and when it binds to the other subunit of the enzyme, the enzymatic activity is lost.Analysis of the mRNA sequence identifies a mutation in the 3′ region of a gene that has turned a UAA codon to UUA.Based on this modification, the clinical researcher hypothesizes that during the elongation cycle in the patient, there is a failure to recruit the _______ at the correct site in the mRNA sequence.This results in the translation of an abnormally long peptide.
