3.1.26.5 | malfunction | inactivation of RNase P results in decreased transcription of several non-coding RNAs in a cell cycle-dependent fashion | Homo sapiens |
3.1.26.5 | physiological function | native nuclear RNase P has an RNase P RNA plus nine RNase P proteins. All subunits are essential for RNase P activity and cell viability. Only the nuclear-encoded RPM2 is known and shown genetically to be required for mitochondrial RNase P activity | Saccharomyces cerevisiae |
3.1.26.5 | physiological function | native nuclear RNase P has an RNase P RNA plus ten RNase P proteins. The protein-only mitochondrial RNase P is composed of three proteins (MRPP1-MRPP3). MRPP1, which methylates G9 of tRNAs, may be responsible for substrate recognition. RNase P RNA is weakly active without RNase P proteins, some activity is present when reconstituted with RPP21 and RPP29 | Homo sapiens |
3.1.26.5 | physiological function | the holoenzyme consists of a single RNase P RNA associated with RNase P protein subunits | Escherichia coli |
