Tyrosine metabolism in connective tissue disease

Ontogeny of Soluble and Mitochondrial Tyrosine Aminotransferases

“…The cl gene of A should be similar in size to the repressor gene of phage 434, since the molecular weights are similar (20). At present it is difficult to speculate on the meaning of the short region of apparent homology within the unpaired i434/ + segment, probably within gene cl (Fig.…”

“…McCann et al (20), described slight elevations of pHPP in urine from patients with connective tissue disease or liver disease. An understanding of both normal and defective tyrosine metabolism must take cognizance of the existence of the two tyrosine metabolizing systems.…”
