Sequence similarity network of all ABPs. a At low stringency, amylase-binding proteins cluster into six families: AbpA (red), AbpB (yellow) and Abp Novel (blue). At high stringency, AbpA separates into two interrelated subfamilies. b Sequence similarity network of AbpA subgroups at high stringency. Each AbpA is color-coded according to its classification into one of the five subgroups defined by the N-terminal sequence, a putative amylase-binding motif
