| Enzyme name: alg13p UniProt ID: P53178* CAZy family: GT1 Gene name: ALG13 Gene GenBank ID: 852835* | Synthesized dimer: bDGlcpN(1-4)bDGlcpN Donor (ID 33944): Ac(1-2)?DGlcpN(1-P-P-5)xXnucU Acceptor (ID 34846): Ac(1-2)bDGlcpN(1-P-P-1)Subst // Subst = dolichol Status: direct evidence in vivo Confirmation methods: mutation; overexpression; in vitro (membrane preparation); in vitro (inhibition); in vitro (purified protein) ID: 247 Notes: Alg13 and Alg14 are required for the second step of lipid-linked oligosaccharide biosynthesis in Saccharomyces cerevisiae. Alg14p functions as a membrane anchor that recruits Alg13p to the cytosolic face of the ER, where catalysis of GlcNAc2-PP-dol occurs. Alg14 is a membrane protein that recruits the soluble Alg13 catalytic subunit from the cytosol to the face of the endoplasmic reticulum. Alg13p associates with Alg14p to form an active transferase catalyzing the biosynthesis of GlcNAc(2)-PP-Dol. | Organism (ID 16681,16727,16890,16891,16892,16893,16894,16895,16896,16897,16898,16899,16900,16901,16902,16903,16904,16905,16906,16907,16908,16909,16910,16911,16912,16913,16914,16915,16916,16917,16918,16919,16920,16921,16922): Saccharomyces cerevisiae SS330, W303-1A, R1158, W303a, XGY31, XGY151, XGY154, XGY155, SKY202, SKY203, XGY156, XGY158, XGY166, XGY167A, XGY168, W303-1B, MHY1409, XGY160, NAY13, WCG4a, WCG4-11/22a, NAY19, NAY20, NAY26, NAY105-1, NAY110-10.1b, NAY110-10.5d, NAY110-12.5b, NAY111-11.9a, NAY111-11.9d, NAY111-13.7c, SKY20, XGY11, ALG13-tetOp, ALG14-tetOp Full structure (ID 34847): Molecule role (precursor of): N-glycan | O’Reilly et al. 2006 DOI: 10.1021/bi060878o Chantret et al. 2005 DOI: 10.1074/jbc.M413941200 Gao et al. 2005 DOI: 10.1074/jbc.M507569200 Averbeck et al. 2008 DOI: 10.1091/mbc.E07–10–1077 Averbeck et al. 2007 DOI: 10.1074/jbc.M704410200 Lu et al. 2012 DOI: 10.1093/glycob/cwr162 Bickel et al. 2005 DOI: 10.1074/jbc.M506358200 |

Both Chs1 and Chs2 collaborate in the repair synthesis of chitin, whereas Chs1 cannot substitute for Chs2 in septum formation.

Chitin synthase 2 has a region whose sequence is highly conserved in all chitin synthases.Substitutions of conserved amino acids in this region with alanine identified 2 domains in which any conserved amino acid could not be replaced by alanine to retain enzyme activity.
