THE ISOLATED SAMPLE DOES NOT HAVE THE SAME NUMBER OF AMINO ACID RESIDUES CODED IN DNA FOR PROTEIN ...THE ISOLATED SAMPLE DOES NOT HAVE THE SAME NUMBER OF AMINO ACID RESIDUES CODED IN DNA FOR PROTEIN PUFX (CHAIN B). PUFX HAS 82 AMINO ACID RESIDUES BASED ON ITS DNA SEQUENCE. IT HAS BEEN SHOWN TO BE POSTRANSLATIONALLY MODIFIED AND THE LAST 12 RESIDUES ARE ABSENT (RATCLIFFE ET AL (2011), BIOCHIMICA ET BIOPHYSICA ACTA,1807,95-107).
