Abstract:
A cDNA library for porcine skeletal muscle was established in the vector pBR322. The library was screened with an oligonucleotide probe coding for a hexapeptide from glucosephosphate isomerase (Gpi). A positive clone with an insert of about 450 bp and restriction sites for PstI, BamHI and PvuII was isolated. A 362-bp PstI fragment was sequenced and shown to contain the codons for the hexapeptide as well as the remaining 29 amino acids of this Gpi peptide. The PstI fragment was used to probe pig genomic DNA. The restriction enzymes PvuII and SacI detected a set of polymorphisms with five bands, behaving as a set of insertion/deletion polymorphisms.
