Rat lung glutathione S-transferases (GST) III (pI 6.8) and IV (pI 6.0) have two immunologically and kinetically distinct Yb types of subunits and these subunits are immunologically similar to the corresponding subunits of liver GST. It is demonstrated that GST III (pI 6.8) and IV (pI 6.0) of rat lung are heterodimers of Ya and Yb type of subunits, a combination not observed among liver GST. Unlike the Yb type subunits of rat liver GST, the Yb type subunits of rat lung GST hybridize with the Ya type subunits in vitro.
