Description
A pyridoxal-phosphate protein. L-Phenylalanine can act instead of L-tyrosine. The mitochondrial enzyme may be identical with EC 2.6.1.1 (aspartate transaminase). The three isoenzymic forms are interconverted by EC 3.4.22.32 (stem bromelain) and EC 3.4.22.33 (fruit bromelain). The enzyme can also catalyse the final step in the methionine-salvage pathway of Klebsiella pneumoniae
