3.E.1.4.6
Possible chaperone membrane protein related to Hsp30, Mrh1 (320 aas; 33% identical to Hsp30p). This protein and its two paralogues, Hsp30 and YR02, are induced by heat shock and are present primarily in the plasma membrane (Wu et al. 2000).  It plays a role in acetic acid tolerance and may be an acetic acid exporter (Takabatake et al. 2015).
