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
A, B	PF13522	Glutamine amidotransferase domain (GATase_6)	Glutamine amidotransferase domain	This domain is a class-II glutamine amidotransferase domain found in a variety of enzymes, such as asparagine synthetase and glutamine--fructose-6-phosphate transaminase.	Domain
