Putative pentitol PTS permease, IIABC.  Induced by arabitol, but this pentitol did not appear to be a substrate.  Encoded within an operon that also encodes a putative polyol-P dehydrogenase and enzymes of the pentose phosphate pathway (PPP) (Kentache et al., 2016, manuscrpt accepted for publication).
