A minor form of starch branching enzyme in potato (Solanum tuberosum L.) tubers has a major effect on starch structure: cloning and characterisation of multiple forms of SBE A (1999), Plant J., 18, 163-171.

EC Number	Cloned (Comment)	Organism
2.4.1.18	expression in Escherichia coli. Multiple forms of the enzyme exist which differ mainly in the length of a polyglutamic acid repeat at the C-terminus of the protein, SBE A1 to SBE A-6. Expression of an antisense SBE A RNA in transgenic potato	Solanum tuberosum
