DescriptionN-Acetyl-L-glutamate 5-semialdehyde is an intermediate in urea cycle and metabolism of amino groups. N-Acetyl-L-glutamate 5-semialdehyde is the second to last step in the synthesis of L-ornithine and is converted from N-acetyl-L-glutamate 5-phosphate via the enzyme N-acetyl-gamma-glutamyl-phosphate reductase [EC 1.2.1.38]. It is then converted to N-acetylornithine via the enzyme acetylornithine aminotransferase [EC 2.6.1.11].
