Chain A,B (GFA1_CANAL | P53704)

molecular function
	GO:0030246	carbohydrate binding	Interacting selectively and non-covalently with any carbohydrate, which includes monosaccharides, oligosaccharides and polysaccharides as well as substances derived from monosaccharides by reduction of the carbonyl group (alditols), by oxidation of one or more hydroxy groups to afford the corresponding aldehydes, ketones, or carboxylic acids, or by replacement of one or more hydroxy group(s) by a hydrogen atom. Cyclitols are generally not regarded as carbohydrates.
	GO:0004360	glutamine-fructose-6-phosphate transaminase (isomerizing) activity	Catalysis of the reaction: beta-D-fructose 6-phosphate + L-glutamine = D-glucosamine 6-phosphate + L-glutamate.
	GO:0008483	transaminase activity	Catalysis of the transfer of an amino group to an acceptor, usually a 2-oxo acid.
	GO:0016740	transferase activity	Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
biological process
	GO:0006048	UDP-N-acetylglucosamine biosynthetic process	The chemical reactions and pathways resulting in the formation of UDP-N-acetylglucosamine, a substance composed of N-acetylglucosamine, a common structural unit of oligosaccharides, in glycosidic linkage with uridine diphosphate.
	GO:1901137	carbohydrate derivative biosynthetic process	The chemical reactions and pathways resulting in the formation of carbohydrate derivative.
	GO:0005975	carbohydrate metabolic process	The chemical reactions and pathways involving carbohydrates, any of a group of organic compounds based of the general formula Cx(H2O)y. Includes the formation of carbohydrate derivatives by the addition of a carbohydrate residue to another molecule.
	GO:0006038	cell wall chitin biosynthetic process	The chemical reactions and pathways resulting in the formation of cell wall chitin, a linear polysaccharide consisting of beta-(1->4)-linked N-acetyl-D-glucosamine residues, found in the walls of cells.
	GO:0035690	cellular response to drug	Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a drug stimulus. A drug is a substance used in the diagnosis, treatment or prevention of a disease.
	GO:0006031	chitin biosynthetic process	The chemical reactions and pathways resulting in the formation of chitin, a linear polysaccharide consisting of beta-(1->4)-linked N-acetyl-D-glucosamine residues.
	GO:0006042	glucosamine biosynthetic process	The chemical reactions and pathways resulting in the formation of glucosamine (2-amino-2-deoxyglucopyranose), an aminodeoxysugar that occurs in combined form in chitin.
	GO:0006541	glutamine metabolic process	The chemical reactions and pathways involving glutamine, 2-amino-4-carbamoylbutanoic acid.
	GO:0030448	hyphal growth	Growth of fungi as threadlike, tubular structures that may contain multiple nuclei and may or may not be divided internally by septa, or cross-walls.
	GO:0006487	protein N-linked glycosylation	A protein glycosylation process in which a carbohydrate or carbohydrate derivative unit is added to a protein via the N4 atom of peptidyl-asparagine, the omega-N of arginine, or the N1' atom peptidyl-tryptophan.
