WebJun 20, 2024 · Ribosome biogenesis is one of the most energy demanding processes in the cell. In eukaryotes, the main steps of this process occur in the nucleolus and include pre-ribosomal RNA (pre-rRNA) processing, post-transcriptional modifications, and assembly of many non-ribosomal factors and ribosomal proteins in order to form mature and … WebApr 14, 2024 · Histone acetylation plays a vital role in organizing chromatin, regulating gene expression and controlling the cell cycle. The first histone acetyltransferase to be identified was histone acetyltransferase 1 (HAT1), but it remains one of the least understood acetyltransferases. HAT1 catalyzes the acetylation of newly synthesized H4 and, to a …
WebJul 31, 2008 · Here, we successfully identified the RNA acetyltransferase (TmcA) responsible for ac 4 C formation at the wobble position of tRNA Met. Despite the purported function of ac 4 C in preventing misreading of the AUA codon, at least in in vitro translation (Stern and Schulman, 1978), a healthy phenotype for the ΔtmcA strain was unexpectedly … WebDec 6, 2024 · The formation of ac4C is closely related to N-acetyltransferase 10 (NAT10) and its helpers, such as putative tRNA acetyltransferase (TAN1) for tRNA ac4C and small …
WebJul 8, 2024 · RNA acetyltransferases contain an N- terminal RNA helicase domain similar to that of DEAD-box RNA helicases paired with a C- terminal Gcn5-related N-acetyltransferase (GNAT) fold. TmcA is a stand-alone enzyme and does not necessitate auxiliary factors for substrate specificity, which is likely due to similar substrates that it acetylates [ 42 ]. WebApr 6, 2024 · In addition, we found an essential gene, KRE33 (human homolog, NAT10), that we renamed RRA1 (ribosomal RNA cytidine acetyltransferase 1) encoding an RNA acetyltransferase responsible for ac4C1773 ...
