Phenotypes of a mutant
''[protein|search|cheV] [protein|search|cheW]'' double mutants exhibit complete loss of chemotaxis [Pubmed|21098025]not essential for pellicle biofilm formation, but mutant is outcompeted by the wild-type strain when competed during pellicle formation [Pubmed|26122431]The protein
Paralogous protein(s)
[protein|search|CheW] (N-terminal domain of CheV)[SW|Domains]
N-terminal [protein|search|CheW]-like domain, C-terminal two-component receiver domain [Pubmed|11553614]Modification
the C-terminal two-component receiver domain is phosphorylated on a Asp residue by [protein|search|CheA] [Pubmed|11553614][SW|Localization]
forms lateral clusters (phosphorylated form), but in the presence of high asparagine concentration (non-phosphorylated form) there is a reversible re-localization to the poles of the cell [Pubmed|21098025][SW|Interactions]
