Biosynthesis of Protein Amino Acids in Plant Tissue Culture. III. Studies on the Biosynthesis of Arginine

摘要

Evidence from isotope competition studies and enzymic studies indicates that n-acetyl glutamic semialdehyde, α-n-acetyl-l-ornithine, l-ornithine and l-citrulline are intermediates between glucose and arginine in cells of Paul's Scarlet Rose. Evidence for the presence of α-n-acetyl-ornithine aminotransferase (E. C. 2.6.1.11) in cell-free extracts was obtained.
