Document Summary
Biochemistry lab exam review appropriate substrates. component at equilibrium. precursors of some amino acids synthesis. derivative pyridoxal phosphate (plp), a prosthetic group present within the transaminase. Transaminases catalyze the transfer of an amino group from one amino acid to a keto acid. The reaction occurs without yielding free nh3; the amino group is retained through the transfer to the vitamin b6. The reaction involves the formation of a schiff base intermediate between the amino acid and the plp (garrett, Glutamate-oxaloacetate transaminase (got) and glutamate-pyruvate transaminase (gpt) are responsible for. The transamination reaction is reversible ( go 0) and can be initiated from either direction by supplying the. The equilibrium constant of this reversible reaction can be determined by measuring the concentration of each. Transaminases play an important role in amino acid metabolism: Urea excretion is the pathway used for elimination of nitrogen by most terrestrial vertebrates.
