This gene is a member of the following regulons
AbrB regulon, RemA regulon, SinR regulon
The gene
Basic information
- Locus tag: BSU34360
Phenotypes of a mutant
Database entries
- BsubCyc: BSU34360
- DBTBS entry: [1]
- SubtiList entry: [2]
Additional information
The protein
Basic information/ Evolution
- Catalyzed reaction/ biological activity: ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate (according to Swiss-Prot)
- Protein family: BY kinase, see the Bacterial Protein Tyrosine Kinase Database)
- Paralogous protein(s): PtkA
Extended information on the protein
- Kinetic information:
- Modification: autophosphorylated on Tyr-225 and Tyr-227 PubMed
- Effectors of protein activity:
Database entries
- BsubCyc: BSU34360
- UniProt: P71051
- KEGG entry: [3]
- E.C. number:
Additional information
Expression and regulation
- Regulatory mechanism:
- Additional information:
- induction by sequestration of SinR by SinI or SlrA PubMed
- the epsA-epsB-epsC-epsD-epsE-epsF-epsG-epsH-epsI-epsJ-epsK-epsL-epsM-epsN-epsO operon is not expressed in a ymdB mutant PubMed
- the amount of the mRNA is substantially decreased upon depletion of RNase Y (this is likely due to the increased stability of the sinR mRNA) PubMed
