A pyridoxal-phosphate protein. L-Phenylalanine can act instead of L-tyrosine. The mitochondrial enzyme may be identical with EC (aspartate transaminase). The three isoenzymic forms are interconverted by EC (stem bromelain) and EC (fruit bromelain). The enzyme can also catalyse the final step in the methionine-salvage pathway of Klebsiella pneumoniae [8].

Rate-limiting Description

"The major differences between the flight group and the synchronous control were elevations in microsomal protein, liver glycogen content, tyrosine aminotransferase, and tryptophan oxygenase and reductions in sphingolipids and the rate-limiting enzyme of heme biosynthesis, delta-aminolevulinic acid synthase."
