Laminarin-induced locus of Polaribacter sp. Hel1_33_49: (a) Differential expression of the genes in laminarin- vs mannose-supplied cells. Ordinate: NSAFs; abscissa: position in the Hel1_33_49 genome (large contig; Supplementary Figure S4D). (b) Gene arrangement of the locus as well as similar loci in other Flavobacteriaceae, including Polaribacter sp. Hel1_85 (see Supplementary Figure S5B); numbers indicate GH families (nc=not classified); species that have been shown to use laminarin in cultivation experiments are marked by an asterisk (*); species where laminarin usage is supported by proteomics are marked by a hash (#).
