Structural highlights
Function[R1A_CVHSA] The papain-like proteinase (PL-PRO) is responsible for the cleavages located at the N-terminus of replicase polyprotein. In addition, PL-PRO possesses a deubiquitinating/deISGylating activity and processes both 'Lys-48'- and 'Lys-63'-linked polyubiquitin chains from cellular substrates. Antagonizes innate immune induction of type I interferon by blocking the phosphorylation, dimerization and subsequent nuclear translocation of host IRF-3.[1] [2] [3] 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 (By similarity). Also contains an ADP-ribose-1-phosphate (ADRP)-binding function.[4] [5] [6] Nsp7-nsp8 hexadecamer may possibly confer processivity to the polymerase, maybe by binding to dsRNA or by producing primers utilized by the latter.[7] [8] [9] Nsp9 is a ssRNA-binding protein.[10] [11] [12] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe NMR structure of the severe acute respiratory syndrome coronavirus nonstructural protein (nsp) 7 in aqueous solution at pH 6.5 was determined and compared with the results of previous structure determinations of nsp7 in solution at pH 7.5 and in the crystals of a hexadecameric nsp7/nsp8 complex obtained from a solution at pH 7.5. All three structures contain four helices as the only regular secondary structures, but there are differences in the lengths and sequence locations of the four helices, as well as between the tertiary folds. The present study includes data on conformational equilibria and intramolecular rate processes in nsp7 in solution at pH 6.5, which provide further insights into the polymorphisms implicated by a comparison of the three presently available nsp7 structures.
