Putative sequential events in the synthesis and remodeling of β-(1,3) glucan.1) Synthesis of linear glucan chains (glucan synthase complex composed of a catalytic [GS], FKS/GSC, activating [Act], and RHO1, regulating [Reg] subunits). 2) Hydrolysis of glucans. 3) Branching of β-(1,3) glucan. 4) Elongation of β-(1,3) glucan side chains. 5) Cross-linking with branched [β-(1,3)] glucan. Glycosylphosphatidylinositol (GPI)-anchored transglycosidase or hydrolases (T) bound to the membrane can act on the polysaccharides in the cell wall space [re-produced from (Gow et al., 2017) with permission, license number (1131560–1)].
