Abstract

A hemagglutinin with an M(r) of 67,000 (pMGA) from Mycoplasma gallisepticum S6 was purified by using monoclonal antibody affinity chromatography. Purified pMGA was treated with a number of enzymes, the resultant peptides were purified, and their amino acid sequence was determined by using an Applied Biosystems (model 471A) protein sequencer. The DNA sequence encoding two peptides was used to dictate the sequences of synthetic oligonucleotides which were used to screen a library of EcoRI-cut M. gallisepticum DNA in pUC18. A clone reactive to both probes was isolated and found to contain a recombinant insert of 10 kb. The clone was mapped by using restriction endonucleases and fragments subclo..
