This family includes Orotidine 5'-phosphate decarboxylase enzymes EC:4.1.1.23 that are involved in the final step of pyrimidine biosynthesis. The family also includes enzymes such as hexulose-6-phosphate synthase. This family appears to be distantly related to Pfam:PF00834.	Domain

SIS (Sugar ISomerase) domains are found in many phosphosugar isomerases and phosphosugar binding proteins. SIS domains are also found in proteins that regulate the expression of genes involved in synthesis of phosphosugars. Presumably the SIS domains bind to the end-product of the pathway.	Domain
