Phenotypes of a mutant
''[gene|56E391BD4C154A603FFD06CEC7BC5615AAC5AD04|cheV] [gene|887D84520DF3D5F22DED525C1C17130EDE60DC36|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
[wiki|Domains]
N-terminal [protein|887D84520DF3D5F22DED525C1C17130EDE60DC36|cheW]-like domain, C-terminal two-component receiver domain [Pubmed|11553614]
[wiki|Response regulatory domain] (aa 176-302) (according to UniProt)
CheW-like domain (aa 16-154) (according to UniProt)
Structure
[AF|P37599]
Modification
the C-terminal two-component receiver domain is phosphorylated on a Asp residue by [protein|6B3B222E56BF0C95A2371CA5208B5522B44D4689|cheA] [Pubmed|11553614]
Paralogous protein(s)
[protein|887D84520DF3D5F22DED525C1C17130EDE60DC36|cheW], (N-terminal domain of CheV)
[wiki|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]
