RNA polymerase is a multi-subunit enzyme that consists of a core enzyme and a sigma factor. The core enzyme is responsible for the synthesis of the RNA chain, while the sigma factor helps the enzyme to bind to the DNA template and to initiate transcription. The transcription process begins ...
Despite intensive genomic studies of Mycoplasma species, little is known regarding conserved transcriptional mechanisms of these bacteria including the contribution of RNA polymerase (RNAP) sigma factors. It was believed that Mycoplasma species have mainly one sigma factor resembling RpoD subunit, while on...
相关研究发表在Nucleic Acids Research:Lysine acetylation of the housekeeping sigma factor enhances the activity of the RNA polymerase holoenzyme,文章通讯作者为You-Hee Cho和Jung-Hye Roe。 他们发现,乙酰化的HrdB加强了HrdB与RNAP全酶的互作。 通过LC-MS/MS分析发现,位于sigma因子的1.2和 2区的赖氨酸(K259...
