Abstract

A sensitive immunoassay developed previously was used to isolate a series of clones expressing cellulase genes from . The clones fell into three groups. Clones in the first group contained plasmids with a 6.6 kb insert of DNA, were strongly antigenic, and contained low levels of CM-cellulase activity. Those in the second group contained plasmids with a 5.0 kb insert, were weakly antigenic, and contained high levels of CM-cellulase activity. Those in the third group contained plasmids with a 5.6 kb insert, were weakly antigenic, and contained low levels of CM-cellulase activity. Restriction analysis showed that the three groups carried different cellulase genes. All of these CM-cellulase activities were exported to the periplasm in . but with different efficiencies. These activities represented important components of the cellulase complex. Their properties indicated that they were different from each other and that they probably had complementary actions.
