Sequences used in the phylogenetic analysis All amino acid sequences and conserved domain searches of known GBEs were obtained from the National Center for Biotechnology Information database (http://www.ncbi.nlm.nih.gov): Aquifex aeolicus VF5 (gi.15606119), Bacillus cereus (674471943), Bacillus subtilis 168 (16080150), Deinococcus geothermalis DSM 11300 (94555367), Deinococcus radiodurans R1 (15806848), Escherichia coli K-12 MG1655 (16131306), Mycobacterium tuberculosis (631464201), Salmonella enterica serovar Typhi Ty21a (485084115), Thermococcus kodakarensis KOD1 (74502442), Thermus thermophiles (504323830), Vibrio cholerae (669407972), Vibrio parahaemolyticus (505126546), and Vibrio vulnificus MO6-24/O (319933217).

Glycogen extraction and side-chain distribution analysis: After cell growth reach late exponential phase, 1.0% maltose (w/v in final) was added. Cells were harvested by centrifugation by 2 h time intervals after c-source addition. Glycogen was extracted and analyzed as described by Park et al. previously (J. Bacteriol. 193(10):2517-2526, 2011). Control means that glycogen was injected directly without debranching by isoamylase. References for supplementary materials 1. Park, J.
