Products & Information Collection of New variant SARS-COV-2 (2019nCOV) -The New York variant B.1.526 lineage

The world is in midst of the COVID-19 pandemic. Recently a new SARS-CoV-2 (2019nCOV)lineage (B.1.526) emerged in New York and spread rapidly. The New York variant B.1.526 lineage is characterised by six lineage-defining mutations in the spike protein, including D614G mutation and one at important residues in the receptor-binding domain (S477N or E484K)1.The combination of E484K or S477N with a D253G mutation of the B.1.526 lineage that might confer immune escape and the increased number of COVID-19 cases². The position S477 is shown be S477N or S477G.

Mutations of Spike protein in SARS-COV-2 (2019nCOV) B.1.526 lineage spread in New York

One spike mutation is at key residues in the RBD (S477N or E484K), two are in the N-terminal domain (T95I and D253G) and one is in loop 2 (A701V) ¹. The position S477 is shown be S477N or S477G.
