amylopectin	enzyme form SBE II is more active than enzyme form SBE I. The enzyme forms SBE I and SBE II mainly branch the dextrins by intrachain branching.The products of SBE I show distinct populations at DP11-12 and DP29-30. The products of enzyme form SBE II habe one, broader, population with a peak at DP13-14. An accumulation of 6-7 chains is seen with both isoforms	Solanum tuberosum	amylopectin with additional alpha-1,6-glucosidic linkages	-	?
