The Cellulose Synthase Superfamily

Abstract

The availability of a nearly complete genome se- quence for Arabidopsis has created many novel op- portunities to identify, by computational methods, the genes that encode enzymes, which have been difficult to characterize by conventional means. We have used this approach to identify a large family of genes of unknown function that show sequence sim- ilarity to cellulose synthase. Our working hypothesis is that these genes encode enzymes that catalyze the synthesis of non-cellulosic polysaccharides (Cutler and Somerville, 1997).
