Sugar uptake and utilization in Spiroplasma spp. Comparison of the phosphotransferase system (PTS) transporters and enzymes involved in sugar uptake and utilization between Spiroplasma melliferum and S. citri. (A) Genes shared between S. melliferum and S. citri (B) S. melliferum-specific systems, genes that were present in S. melliferum and absent in S. citri were highlighted in red. Abbreviations: N-acetylglucosamine (GlcNAc); N-acetylmuramic acid (MurNAc).
