Rnasep is not a protein but a ribozyme

WebThe hammerhead ribozyme has been thought of as a ‘‘prototype’’ ribozyme in the same sense that lysozyme and serine proteases have been thought of as ‘‘prototype’’ conventional protein enzymes, and for that reason the hammer-head ribozyme has attracted intense experimental scrutiny. The hammerhead

WebDefinition. Ribozymes are catalytically active RNA molecules or RNA–protein complexes, in which solely the RNA provides catalytic activity. The term ribozyme refers to the … WebS. coelicolor contains RNase P (Kim et al., 2000) so it is possible that RNase ES is involved in processing the RNA component of that ribozyme. The effects of the rns null mutation on antibiotic production by S. coelicolor were not examined in the studies of the Cohen group. Comparative studies in E. coli and S. coelicolor may bear on that issue. command prompt google closes https://unique3dcrystal.com
