2.4.1.18	additional information	each isoform of the Q-enzyme plays a distinct role in starch biosynthesis	
2.4.1.18	additional information	starch-branching enzyme and glycogen synthase work in a cyclically interdependent fashion	
2.4.1.18	additional information	differences in properties between isoforms of SBE are not the main factors that determine the polymodal distribution of branch lengths in amylopectin	
2.4.1.18	additional information	each branching enzyme isoform is involved in a different phase of glycogen synthesis	
2.4.1.18	additional information	the enzyme is responsible for the formation of the alpha-1,6 linkages in the glycogen molecule	
2.4.1.18	additional information	a fatal form of glycogen storage disease IV affects Norwegian Florest Cat, in which striated muscles and the nervous system are primarily affected, while the liver remains unaffected. This form of GSD IV is caused by a 6.1-kb deletion that eliminates exon 12 of the feline GBE1 gene	
2.4.1.18	additional information	glycogen branching enzyme GBE1 mutation causing equine glycogen storage disease IV.A C to A substitution at base 102 results in a tyrosine (Y) to stop (X) mutation in codon 34 of exon of exon 1. All 11 affected foals are homozygous for the X34 allele, all 16 control horses are homozygous for the Y34 allele. Poorly branched glycogen, abnormal polysaccharide accumulation, lack of measurable GBE1 enzyme activity and immunodetectable GBE1 protein, coupled with the present observation of abundant GBE1 mRNA in affected foals, are consistent with the nonsense mutation in the 699 amino acid GBE1 protein	
2.4.1.18	additional information	in absence of starch-branching enzyme IIb, the further absence of starch-branching enzyme Ia leads to increased branching	
2.4.1.18	additional information	Multiple isoforms of starch branching enzyme-I exist in wheat. Lack of the major SBE-I isoform does not alter starch phenotype	
2.4.1.18	additional information	no major difference in the amylose/amylopectin ratio is detectected by reducing the expression of SBE-I using antisense constructs	
2.4.1.18	additional information	starch structure in the two accessions, overview	
2.4.1.18	additional information	the enzyme catalyzes starch branching by the cleavage of alpha(1->4) linkage and transfer in alpha(1->6) of the fragment in non-reducing position, but the enzyme also shows an additional alpha-4-glucanotransferase activity not described so far for a member of the GH13 family. The enzyme is able to transfer alpha(1->4)-linked-glucan in C4 position (instead of C6 position for the branching activity) of a glucan to create new alpha(1->4) linkages yielding to the elongation of linear chains subsequently used for further branching, overview	
2.4.1.18	additional information	the glycogen branching enzyme from Vibrio vulnificus transfers short side chains (DP 3-5) significantly greater than any other bacterial glycogen branching enzyme. The N1-domain of the enzyme has a crucial role in the determination of the branching pattern of glycogen, degrees of polymerization in enzyme reaction products compared to enzymes from other origin, overview
