Comparative analysis of predicted glycogen and trehalose metabolic pathways in Arthrobacter species. Glycogen and trehalose metabolism-associated genes are colored, as indicated below the figure. The figure shows the differences in direction, presence, and location of genes among the strains. GH65: α,α-trehalose phosphorylase; GH13_30: α-1,4-glucan-maltose-1-phosphate maltosyltransferase; TreY/GH13_26: 1→4;-α-D-glucan 1-α-D-glucosylmutase; MalQ: 4-α-glucanotransferase; 2.4.1.21: glycogen synthase, and ADP-glucose transglucosylase; OtsA/ GT20: trehalose 6-phosphate synthase; 3.2.1.28: α-trehalase; GalU: UTP-glucose-1-phosphate uridylyltransferase; GlgX/CBM + GH13_11: glycogen debranching protein; TreZ/GH13_10: malto-oligosyltrehalose trehalohydrolase, α-glucosidase, and α-trehalase; GlgA/GT20: glycogen synthase, and ADP-glucose transglucosylase; GlgC: glucose-1-phosphate adenylyltransferase; OtsB/GT20: trehalose 6-phosphate phosphatase; 2.7.1.201: PTS system, and sugar-specific IIA component; GlgB/CBM + GH13_9: 1,4-α-glucan branching enzyme; TreS/GH13_16: maltose α-D-glucosyltransferase/α-amylase; GlgE/GH13_3: α-1,4-glucan-maltose-1-phosphate maltosyltransferase, PTS system, and sugar-specific IIA component; GlgP: glycogen phosphorylase; and 3.2.1.10: oligo-1,6-glucosidase. The black circle indicates our strain. / mean one gene deletion and // mean two more than genes deletion
