Introduction
A genomic library was constructed by partial digestion with EcoRI/BamHI and BgII/XhoI followed by ligation of the DA fragments into EcoRI/XhoI abd BgII/XhoI site of the cosmid vector pET29bEBBX. Oligonucleotide primers were synthesized by Intergrated DNA technologies (IDT),Inc, Coraville, IA. Nucleotide sequence analysis was analysed using Lasergene Megasoftware. Database search was done using Basic Local Alignment Search Tool (BLAST). Sequence Compilation Sequence Alignment.
