Web12 hours ago · To determine which of the juxtamembrane cysteine residues are S-palmitoylated, we tested whether the decreased S-palmitoylation signals of the C 5 A mutant could be restored by abolishing one of the five cysteine-to-alanine mutations at Cys-147, Cys-155, Cys-357, Cys-522 and Cys-540 (designated A147C, A155C, A357C, A522C …
WebIt was found that mutations preventing nsP1 palmitoylation also attenuated virus replication. The replacement of these cysteines by alanines, or their deletion, abolished virus viability, possibly due to disruption of interactions between nsP1 and nsP4, which is the catalytic subunit of the replicase. software gestionale per negoziWebCys to Ala mutations in this context would be considered non-conservative.
