26. Beta-glucan synthesis-associated protein KRE6
General function:
Carbohydrate transport and metabolism
Specific function:
Involved in the synthesis of (1->6)- and (1->3)-beta-D- glucan polymers of the yeast cell wall in vivo. It is required for full activity of beta-glucan synthase in vitro. May be involved in the maturation and transport of cell wall proteins (CWP) to the cell wall. May act as a transglucosidase and contribute to the construction of a protein-bound glucan-structure that acts as an acceptor site for the addition of (1->6)-beta-D-glucan at the cell surface
