Discussion: Importantly, they also inferred that the Pro323Leu mutation occurred on an Asp614Gly background.

Discussion: They identified that the Pro323Leu mutation in the RNA-dependent RNA polymerase led to the rapid spread of the virus, rather than the previously reported Asp614Gly mutation in the spike glycoprotein.

Discussion: Another important amino acid substitution P323L in RNA dependent RNA polymerase (RdRP) protein was recorded in 16 viral strains sequenced in this study.

The emergence and ongoing convergent evolution of the SARS-CoV-2 N501Y lineages.

PMID: 34537136 2021 Cell

Introduction: Other than the early identification of the D614G substitution in the viral Spike protein and P323L in the viral RNA-dependent RNA polymerase protein, both of which may have increased viral transmissibility without impacting pathogenesis, few mutations were epidemiologically significant and the evolutionary dynamics of the virus were predominantly characterized by a mutational pattern of slow and selectively neutral random genetic d

Figure: Also included for reference are sites previously detected to be evolving under positive selection such as S/614, the site of the D614G mutation that is present in all three of the 501Y lineages, S/5, and RdRp/P323L (ORF1b/314).

Discussion: About 65.6% of the viruses belong to clades 20A, 20B, and 20C and non-synonymous mutations leading to two amino acid substitutions, the D614G in the spike and P323L in nsp12, were predominant in most countries.

Discussion: It should be noted, the P323L substitution has been frequently observed in nsp12 in the strain spreading in Africa.

COVID-19 outbreak in Malaysia: Decoding D614G mutation of SARS-CoV-2 virus isolated from an asymptomatic case in Pahang.

PMID: 34557346 2021 PeerJ

Result: In addition to the S-protein D614G mutation, other missense mutations were identified in NSP12 (RNA dependent RNA polymerase; RdRp) with a P323L mutation, a T85I mutation in

Discussion: Our current findings are consistent with this observation, in that the viral genome sequences of the SARS-CoV-2 strains from Cases 1-4 harbored both the D614G and P323L mutations.

Discussion: Previous studies have shown that the P323L mutation in NSP12 co-evolved with the D614G mutation in S-protein.

SARS-CoV-2 promotes RIPK1 activation to facilitate viral propagation.

PMID: 34663909 2021 Cell research

Abstract: Furthermore, NSP12 323L variant, encoded by the SARS-CoV-2 C14408T variant first detected in Lombardy, Italy, that carries a Pro323Leu amino acid substitution in NSP12, showed increased ability to activate

Discussion: Furthermore, the increased ability of SARS-CoV-2 323L variant to stimulate RIPK1 activation and replicate in the lung organoids also suggests that the NSP12 P323L mutation may contribute to the spread of this SARS-CoV-2 variant around the world.

Discussion: In addition, since the structural changes in NSP12 introduced by P323L mutation may contribute to the resistance to remesdesivir, RIPK1 inhibition may offer a therapeutic strategy to reduce viral propagation.

Changing predominant SARS-CoV-2 lineages drives successive COVID-19 waves in Malaysia, February 2020 to March 2021.

Result: Nonsynonymous mutations seen in the B.1.524 lineage sequences were nsp3-T1198I, nsp4-T28I, nsp5-T24A, nsp12-P323L, nsp13-L428F, spike-D614G, spike-A701V, and N-S194L.

Discussion: The nsp12 (RNA-dependent RNA polymerase) P323L mutation present in lineage B.1.524 is almost always associated with
