Predicted types of transporters identified in the M. mackini genome and differences with the microsporidian sets. The red question marks stand for metabolite exchanges that are supposed to happen, but for which no good candidate gene was detected. Next to each transporter predicted for M. mackini, a small plot shows which of the representative microsporidians have corresponding homologous genes. The set differs in many details between mikrocytids and microsporidians, as well as within microsporidians (as a further note, while microsporidians lack ABCA transporters, they possess the functionally related ABCG, which is missing in Mikrocytos). AAAP, amino acid/auxin permease; ABC, ATP-binding cassette transporter (types A and C); Ac-CoA, acetyl-CoA transporter; ENT, equilibrative nucleoside transporter; FT, folate transporter; GLUT, glucose transporter; ZIP, zinc/iron permease
