Organism

Vibrio parahaemolyticus serotype O3:K6 (strain RIMD 2210633) [Complete proteome] [HAMAP]

Taxonomic identifier

223926 [NCBI]

Taxonomic lineage

cellular organisms › Bacteria › Proteobacteria › Gammaproteobacteria › Vibrionales › Vibrionaceae › Vibrio › Vibrio harveyi group › Vibrio parahaemolyticus

Protein attributes

Sequence length	112 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Phosphorelay protein which receives a sensory signal from a sensor kinase and transmit it to LuxO. At low cell density, a phosphoryl group is transferred from the sensor kinase, probably on His-56 and this phosphoryl group is further transferred to LuxO.
Subunit structure	Monomer By similarity.
Sequence similarities	Contains 1 HPt domain.
