SDS-PAGE analysis of culture supernatants after 120Â h. Transformants were induced by methanol as indicated, and the supernatants (pHÂ =Â 6.0) after 120Â h were analyzed by SDS-PAGE. Lane M, molecular weight marker; lane 1 MPH; lane 2 CHBD-MPH; lane 3 CHBD-QR; lane 4 CHBD-DQR. The positions of expressed MPH proteins are indicated by arrows
