(a) Putative membrane topology of PaxB as determined by TMHMM; (b) Alignment of predicted amino acid sequences for PaxB and related proteins from representative fungi within the Eurotiomycetes (Eu) and Sordariomycetes (So). The predicted transmembrane helices, as determined by TMHMM, are indicated by red boxes. Numbers indicate the position of the last amino acid residue displayed. The predicted transmembrane helices in PaxB are labeled I-VII in both panel A and B. Sequences are from P. paxilli (Pp_PaxB, ADO29934), A. flavus (Afl_AtmB, CAP53939), A. fumigatus (Afu_XP_751270), A. nidulans (An_XP_681413), P. chrysogenum (Pc_CAP80269), N. lolii (Nl_LtmB, ABF20226), G. zeae (Gz_XP_384770), N. crassa (Nc_XP_958743) and M. oryzae (MGG_07412).
