URA3
URA3 is a gene on chromosome V in Saccharomyces cerevisiae (yeast). Its systematic name is YEL021W. URA3 is often used in yeast research as a "marker gene", that is, a gene to label chromosomes or plasmids. URA3 encodes Orotidine 5'-phosphate decarboxylase (ODCase), which is an enzyme that catalyzes one reaction in the synthesis of pyrimidine ribonucleotides (a component of RNA).
