This domain covers the NSP16 region of the coronavirus polyprotein. The SARS-CoV RNA cap SAM-dependent (nucleoside-2'-O-)-methyltransferase (2'-O-MTase) is a heterodimer comprising SARS-CoV nsp10 and nsp16. When bound to nsp10, nsp16 is active as a type-0 RNA cap-dependent 2'-O-MTase, ie., active only when the cap guanine is methylated at its N7 position. Nsp10 binds to nsp16 through an activation surface area in nsp10, and the resulting complex exhibits RNA cap (nucleoside-2'-O)-methyltransferase activity. Nsp10 is a double zinc finger protein together with nsp4, nsp5, nsp12, nsp14, and nsp16, nsp10 has been found to be essential in the assembly of a functional replication/transcription complex. NSP16 plays a key role in viral replication as it is involved in immune response evasion through the 2'-O-methylation of coronavirus RNA, which is essential for preventing recognition by the host. It mimics the human protein CMTr1 and, unlike CMTr1, it requires NSP10 as a binding partner to activate its enzymatic activity [4]. Nsp16 adopts a typical fold of the S-adenosylmethionine-dependent methyltransferase (SAM) family as defined initially for the catechol O-MTase but it lacks several elements of the canonical MTase fold, such as helices B and C. The nsp16 topology matches those of dengue virus NS5 N-terminal domain and of vaccinia virus VP39 MTases [1,2, 3]. Structural analysis in NSP16 from SARS-CoV-2 identified a cryptic pocket (also present in other coronavirus such as SARS-CoV-1 and MERS) not present in human CMTr1, and the fact that NSP16 is one of the most conserved proteins of SARS-CoV-2 and related viruses, make it an interesting target for developing new antiviral treatment for COVID-19 and other diseases caused by coronaviruses [5].
