IBV (strain KB8523) Replicase polyprotein 1ab (His)

Description: The replicase polyprotein of coronaviruses is a multifunctional protein: it contains the activities necessary for the transcription of negative stranded RNA, leader RNA, subgenomic mRNAs and progeny virion RNA as well as proteinases responsible for the cleavage of the polyprotein into functional products., NendoU is a Mn(2+)-dependent, uridylate-specific enzyme, which leaves 2'-3'-cyclic phosphates 5' to the cleaved bond. IBV (strain KB8523) Replicase polyprotein 1ab (His) is expressed in Baculovirus insect cells with C-6xHis tag. The predicted molecular weight is 30.1 kDa and the accession number is P12723.
