2) Regulation: Several steps in the leucine pathway are regulated. The branched chain amino acid transferase, which catalyzes the very first step, a transamination, is induced by cortisol and cAMP/PKA. Both regulators are associated with low energy and would be expected to stimulate amino acid catabolism.

Amino Acid Catabolism. Removal of amino group by transamination or deamination. Requires coenzyme derivative of vitamin B6 (pyridoxine) Transamination. Attaches amino group of amino acid. To keto acid. Converts keto acid into amino acid. That leaves mitochondrion and enters cytosol. Available for protein synthesis. Deamination. Prepares amino ...

Each amino acid corresponds to several different codons. Each amino acid corresponds to several different codons. (64 codons are possible, and 20 amino acids exist, with 2 codons signaling for “stop”) The phenotype of an organism is a result of the variations in the proteins produced in this way.

Amino acids that will be catabolized must have their amino groups removed via deamination. The nitrogenous waste is excreted as ammonia, urea, or another waste product. The carbon skeletons are modified by enzymes to intermediates of glycolysis and the citric acid cycle.

5. Some metabolites can be converted to amino acids by transamination, the transfer of an amino acid group to an organic acid. 6. Plants synthesize all the amino acids they need; animals lack some enzymes needed to make some amino acids. 7. Humans synthesize 11 of 20 amino acids; the remaining 9 essential amino acids must be provided by the ...
