WebAug 18, 2024 · In bacteria, sigma factors are crucial in determining the plasticity of core RNA polymerase (RNAP) while promoter recognition during transcription initiation. This process is modulated through an intricate regulatory network in response to environmental cues. Previously, an extracytoplasmic function (ECF) sigma factor, AlgU, was identified to … WebThe regulation of these sigma factors was predicted to be conserved across the Firmicutes, since the regulatory proteins controlling their activation are largely conserved. However, …
WebThis phenomenon, i.e. that a new function emerges that is similar to the constituting functions, is called self-similarity. The Gaussian is a self-similar function. Convolution with a Gaussian is a linear operation, so a convolution with a Gaussian kernel followed by a convolution with again a Gaussian kernel is equivalent to
