isoform SSIIa preferentially elongates outer but not inner chains of amylopectin. Isoform SSIIa can complement most isoform SSI functions that use glucan chains with DP 6-7 to generate DP 8-12 chains but cannot fully compensate for the elongation of DP 16-19 chains. Isoform SSIIa cannot compensate for elongation of DP higher 30 by isoform SSIIIa |
