ABSTRACT:
A full-length cDNA is obtained by analyzing the partial amino acid sequence of purified endo-β-galactosidase C, constructing primers based thereon, effecting PCR with the use of the genomic DNA ofClostridium perfringensas a template to thereby obtain a fragment of cDNA encoding endo-β-galactosidase, effecting cassette PCR by using the cDNA fragment thus obtained to thereby obtain the 5′-terminal and 3′-terminal domains, and further effecting PCR with the use of primers constructed on the basis of the data acquired above.
