Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (GAS2_YEAST | Q06135)
molecular function
    GO:0042124    1,3-beta-glucanosyltransferase activity    Catalysis of the splitting and linkage of (1->3)-beta-D-glucan molecules, resulting in (1->3)-beta-D-glucan chain elongation.
    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:0030476    ascospore wall assembly    The aggregation, arrangement and bonding together of a set of components to form an ascospore wall. During sporulation in Ascomycota, each ascospore nucleus becomes surrounded by a specialized spore wall, formed by deposition of spore wall components in the lumenal space between the outer and inner leaflets of the prospore membrane. An example of this process is found in Saccharomyces cerevisiae.
    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:0071555    cell wall organization    A process that results in the assembly, arrangement of constituent parts, or disassembly of the cell wall, the rigid or semi-rigid envelope lying outside the cell membrane of plant, fungal and most prokaryotic cells, maintaining their shape and protecting them from osmotic lysis.
    GO:0071970    fungal-type cell wall (1->3)-beta-D-glucan biosynthetic process    The chemical reactions and pathways resulting in the formation of (1->3)-beta-D-glucans, compounds composed of glucose residues linked by (1->3)-beta-D-glucosidic bonds, found in fungal cell walls.
cellular component
    GO:0031362    anchored component of external side of plasma membrane    The component of the plasma membrane consisting of the gene products that are tethered to the external side of the membrane only by a covalently attached anchor, such as a lipid group embedded in the membrane. Gene products with peptide sequences that are embedded in the membrane are excluded from this grouping.
    GO:0031225    anchored component of membrane    The component of a membrane consisting of the gene products that are tethered to the membrane only by a covalently attached anchor, such as a lipid group that is embedded in the membrane. Gene products with peptide sequences that are embedded in the membrane are excluded from this grouping.
    GO:0009277    fungal-type cell wall    A rigid yet dynamic structure surrounding the plasma membrane that affords protection from stresses and contributes to cell morphogenesis, consisting of extensively cross-linked glycoproteins and carbohydrates. The glycoproteins may be modified with N- or O-linked carbohydrates, or glycosylphosphatidylinositol (GPI) anchors; the polysaccharides are primarily branched glucans, including beta-linked and alpha-linked glucans, and may also include chitin and other carbohydrate polymers, but not cellulose or pectin. Enzymes involved in cell wall biosynthesis are also found in the cell wall. Note that some forms of fungi develop a capsule outside of the cell wall under certain circumstances; this is considered a separate structure.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0005886    plasma membrane    The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
