Nucleotide sequence of the Saccharomyces cerevisiae arginase gene (CAR1) and its transcription under various physiological conditions

Abstract

We have determined the nucleotide sequence of the yeast CAR1 gene along with its 5' and 3' flanking sequences. The structural portion of this gene encodes a protein of 333 amino acid residues with a calculated Mr value of 35,616. The transcripts produced from this gene are modestly heterogeneous at their 5' and 3' termini. Most 5' termini map to a position 42 to 49 base pairs upstream from the ATG at the beginning of the open reading frame. The 3' termini map to a position 108 to 127 base pairs downstream of the amber codon which terminates the open reading frame. A variety of potentially significant sequences were identified in the regions flanking the structural portion of the gene.
