Protein detail:


Protein name ORF1ab polyprotein
Uniprot protein ID P0C6X7
Protein length 7073 amino acids
Protein description The Orf1ab polyprotein contains the Orf1a polyprotein and 16 non-structural proteins. The Orf1ab polyprotein and its cleavage products carry out a wide range of activities associated with the viral replication, including ATP binding and breaking down of ADP and phosphate, cysteine-directed endopeptidase, leading to the formation of nonstructural proteins, such as exonuclease that produces ribose- 5-phosphate, methyltransferase for the synthesis of new nucleotides, RNA polymerase for the viral replication, RNA helicase for the removal of super twisting, as well as the regulation of the transcription through binding of zinc. However, the functions of the Orf1ab are the collective functions of the non-structural proteins encoded by the gene of Orf1ab
