Function

The papain-like proteinase (PL-PRO) is responsible for the cleavages located at the N-terminus of replicase polyprotein. Activity of PL-PRO is dependent on zinc (By similarity).
The main proteinase 3CL-PRO is responsible for the majority of cleavages as it cleaves the C-terminus of replicase polyprotein at 11 sites. Recognizes substrates containing the core sequence [ILMVF]-Q-|-[SGACN]. Inhibited by the substrate-analog Cbz-Val-Asn-Ser-Thr-Leu-Gln-CMK.
The helicase which contains a zinc finger structure displays RNA and DNA duplex-unwinding activities with 5' to 3' polarity. Its ATPase activity is strongly stimulated by poly(U), poly(dT), poly(C), poly(dA), but not by poly(G) (By similarity).
The exoribonuclease acts on both ssRNA and dsRNA in a 3' to 5' direction.
Nsp7-nsp8 hexadecamer may possibly confer processivity to the polymerase, maybe by binding to dsRNA or by producing primers utilized by the latter.
Nsp9 is a ssRNA-binding protein.
NendoU is a Mn(2+)-dependent, uridylate-specific enzyme, which leaves 2'-3'-cyclic phosphates 5' to the cleaved bond.

Catalytic Activity

a ribonucleoside 5'-triphosphate + RNA(n) = diphosphate + RNA(n+1)
ATP + H2O = ADP + H(+) + phosphate

Subunit

3CL-PRO exists as monomer and homodimer. The three peptides nsp2, nsp3 and nsp4 may form a complex. Nsp9 is a dimer. Eight copies of nsp7 and eight copies of nsp8 assemble to form a heterohexadecamer. Nsp10 forms a dodecamer (By similarity). Interacts with DDX1 (via C-terminus).

Miscellaneous

Produced by -1 ribosomal frameshifting at the 1a-1b genes boundary.

Similarity

Belongs to the coronaviruses polyprotein 1ab family.
