| molecular function |
|---|
| | GO:0004359 | | glutaminase activity | | Catalysis of the reaction: L-glutamine + H2O = L-glutamate + NH3. |
| | GO:0016787 | | hydrolase activity | | Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3. |
| | GO:0016829 | | lyase activity | | Catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. They differ from other enzymes in that two substrates are involved in one reaction direction, but only one in the other direction. When acting on the single substrate, a molecule is eliminated and this generates either a new double bond or a new ring. |
| | GO:0036381 | | pyridoxal 5'-phosphate synthase (glutamine hydrolysing) activity | | Catalysis of the reaction: D-ribose 5-phosphate + D-glyceraldehyde 3-phosphate + L-glutamine = pyridoxal 5'-phosphate + L-glutamate + 3 H2O + phosphate. The reaction occurs in two steps: L-glutamine + H2O = L-glutamate + NH3, and subsequently D-ribose 5-phosphate + D-glyceraldehyde 3-phosphate + NH3 = pyridoxal 5'-phosphate + 4 H2O + phosphate. |
| biological process |
|---|
| | GO:0006543 | | glutamine catabolic process | | The chemical reactions and pathways resulting in the breakdown of glutamine, 2-amino-4-carbamoylbutanoic acid. |
| | GO:0006541 | | glutamine metabolic process | | The chemical reactions and pathways involving glutamine, 2-amino-4-carbamoylbutanoic acid. |
| | GO:0042823 | | pyridoxal phosphate biosynthetic process | | The chemical reactions and pathways resulting in the formation of pyridoxal phosphate, pyridoxal phosphorylated at the hydroxymethyl group of C-5, the active form of vitamin B6. |
| | GO:0008614 | | pyridoxine metabolic process | | The chemical reactions and pathways involving pyridoxine, 2-methyl-3-hydroxy-4,5-bis(hydroxymethyl)pyridine, one of the vitamin B6 compounds. Pyridoxal, pyridoxamine and pyridoxine are collectively known as vitamin B6, and are efficiently converted to the biologically active form of vitamin B6, pyridoxal phosphate. |
| | GO:0042819 | | vitamin B6 biosynthetic process | | The chemical reactions and pathways resulting in the formation of any of the vitamin B6 compounds; pyridoxal, pyridoxamine and pyridoxine and the active form, pyridoxal phosphate. |
| cellular component |
|---|
| | GO:0005829 | | cytosol | | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| | GO:1903600 | | glutaminase complex | | A protein complex which is capable of glutaminase activity. |
