This gene is a member of the following regulons
The gene
Basic information
- Locus tag: BSU30630
Phenotypes of a mutant
Database entries
- DBTBS entry: [1]
- SubtiList entry: [2]
Additional information
The protein
Basic information/ Evolution
- Catalyzed reaction/ biological activity:
- removal of pyrophosphate from the 5' end of mRNAs to make the RNA accessible for degradation by RNases PubMed
- RppH requires at least two unpaired nucleotides at the 5' end of its RNA substrates and prefers three or more. The second of these 5'-terminal nucleotides must be G, whereas a less strict preference for a purine is evident at the third position, and A is slightly favored over G at the first position PubMed
- Protein family: Nudix hydrolase family (according to Swiss-Prot)
