Abstract
A genomic clone bank of Paracoccus denitrificans DNA has been constructed in the expression vector set pEX1, pEX2, and pEX3. Screening of this clone bank with antibodies raised against P. denitrificans methanol dehydrogenase resulted in the isolation of a clone, pNH3, that synthesized methanol dehydrogenase cross-reactive proteins. The nucleotide sequence of the P. denitrificans DNA fragment inserted in this clone has been determined and shown to contain the full methanol dehydrogenase structural gene. DNA cross-hybridization was found with DNA fragments which have been reported to contain the methanol dehydrogenase structural genes from Methylobacterium sp. strain AM1 and Methylobacterium organophilum.
