G Consider the compound. This is pyridoxal phosphate (P L P) with several functional groups selected. P L P is a heterocyclic 6 membered ring. The first position is a nitrogen which is selected and labeled D. The carbon in the third position is bound a side chain C H 2 P O 4 2 minus. The phosphate group is selected and labeled A. The carbon in the third position is single bound to a C O H group. The C O H is selected and labeled B. The carbon in the fourth position is single bonded to an O H group. The O H group is selected and labeled C. The carbon in the fifth position is single bonded to an unselected methyl group. Identify the group in pyridoxal phosphate (PLP) that covalently binds enzyme and substrate. D A B C Aminotransferases (transaminases) must deaminate one amino acid and add an amino group to another amino acid during transamination. How do the two processes differ
