We screened nearly one thousand random sequenced targets obtained by partial sequencing of 13 hemiascomycete genomes identified by higher amino acid sequence similarity to a non-Saccharomyces cerevisiae protein than to a S. Cerevisiae protein. Among those sequences we have identified 36 novel phylogenetic clusters of putative transporters which, according to the Transport Commission system (TC-DB, 2002; http:// tcdb.ucsd.edu/tcdb), do not belong to acknowledged S. Cerevisiae protein families [De Hertogh et al.: Funct. Integr. Genomics 2002;2:154-170; http://cbi.labri.u-bordeaux.fr/Genolevures]. These novel hemiascomycete transporters comprise 3 channels, 23 secondary transporters, 5 primary transporters and 5 membrane proteins of unknown function.
