HMM_SP and HMM_gluT scores of MFS porter proteins. a HMM scores for the theoretical ATCC1015 proteome, with HMM_gluT = black dotted line and HMM_SP = orange dotted line. Horizontal lines indicate the HMM_gluT thresholds d _min (dashed) and MCC_max (solid). MFS porter proteins found in the three conditions applied are indicated with filled circles and colour-coded according to their relative abundance patterns. b Close-up of the proteins that scored above the d _min (dashed line) and MCC_max (solid line) thresholds. The galacturonic acid transporter GatA (indicated with a grey triangle and not found in the conditions applied) is added as a reference. With HMM_gluT, the Mst transporters are well separated from GatA, whereas the more general HMM_SP does not discriminate the putative glucose transporters from the galacturonic acid transporter
