GAL1 | Galactokinase; phosphorylates alpha-D-galactose to alpha-D-galactose-1-phosphate in the first step of galactose catabolism; expression regulated by Gal4p; human homolog GALK2 complements yeast null mutant; GAL1 has a paralog, GAL3, that arose from the whole genome duplication. (528 aa) | ||||
TYR1 | Prephenate dehydrogenase involved in tyrosine biosynthesis; expression is dependent on phenylalanine levels; Belongs to the prephenate/arogenate dehydrogenase family. (452 aa) | ||||
ARO4 | Phospho-2-dehydro-3-deoxyheptonate aldolase, tyrosine-inhibited; 3-deoxy-D-arabino-heptulosonate-7-phosphate (DAHP) synthase; catalyzes the first step in aromatic amino acid biosynthesis and is feedback-inhibited by tyrosine or high concentrations of phenylalanine or tryptophan; relative distribution to the nucleus increases upon DNA replication stress. (370 aa) | ||||
ARO3 | Phospho-2-dehydro-3-deoxyheptonate aldolase, phenylalanine-inhibited; 3-deoxy-D-arabino-heptulosonate-7-phosphate (DAHP) synthase; catalyzes the first step in aromatic amino acid biosynthesis and is feedback-inhibited by phenylalanine or high concentration of tyrosine or tryptophan.
