PF01380 | SIS domain (SIS) | SIS 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 domain ... | Domain | |

glutamine-fructose-6-phosphate transaminase (isomerizing) M-CSA #82 | Glucosamine-fructose-6-phosphate aminotransferase (isomerizing) also known as Glucosamine-6-phosphate synthase (GlmS), catalyses the first reaction in hexamine biosynthesis. It belongs to an F-type group of glutamine-dependent amidotransferase family of enzymes, which utilise the glutamine amide nitrogen in the biosynthesis of phosphoribosylamine, glutamate or asparagine. | Defined by 10 residues: CYS:A-1ARG:A-26TRP:A-74ASN:A-98GLY:A-99GLU:A-481LYS:A-485GLU:A-488HIS:A_2-504LYS:A-603 | EC: 2.6.1.16 (PDB Primary Data) |
