Flagellin protein function
WebOct 27, 2024 · This suggests a mechanism where flagellin modification by FlmG can occur before the FlaF-dependent secretion, thus avoiding competition for flagellin binding. Post-translational protein modifications are essential for many cellular functions, but the underlying substrate selectivity remains poorly understood. WebApr 10, 2024 · The effector fusions were co-expressed with the p19 protein, which is a suppressor of RNA silencing that promotes accumulation of the recombinant viruses. The mCherry protein was also co-expressed with p19 and the effector fusion in two of the studies, which provides a non-destructive reporter on virus accumulation and spread.
