Nucleotide sequence of the ARGRII regulatory gene and amino acid sequence homologies between ARGRII PPRI and GAL4 regulatory proteins.

We report here the DNA sequence of the ARGRII gene, one of the three regulatory genes involved in controlling the anabolism and catabolism of arginine in yeast. This gene encodes a protein of 880 amino acids with a deduced molecular mass of about 100 kDa. The ARGRII protein shows significant homology with two other regulatory proteins of yeast, PPRI and GAL4.
