Characterization of Cellulose Synthesis in Plant Cells

Figure 1

Model for structure of CesA proteins (right) shows a conserved zinc finger domain (ZN) and a hyper variable region (HVRΙ) near N-ter of TM1-2 and short C ter of TM3–8 and central hypervariable region (HVRΙΙ), plant-specific conserved region (P-CR), and class specific region (CSR); position of the processive glycosyltransferase motif D,D,D,QXXRW. Plant’s cellulose biosynthesis (left). The plasma membrane-associated sucrose synthase (SuSy) channels uridine diphosphate-glucose (UDP-G) substrate to form rosette and glucan chain formation, the UDP formed can be recycled back to SuSy, and Korrigan cellulase (Kor) has been involved in monitoring of cellulose synthesis. Microtubules (MT) play role to regulate CesA proteins trafficking [2, 54, 72].
