The protein

Catalyzed reaction/ biological activity

• autophosphorylation, phosphorylation of [protein|49E70A20CC05DBE485953C0AE34E634EFB33C3B2|LiaR]
• dephosphorylation of [protein|49E70A20CC05DBE485953C0AE34E634EFB33C3B2|LiaR] in the absence of the stress signal [Pubmed|23279150]

[SW|Domains]

• two transmembrane segments, C-terminal histidine phosphotransferase domain

Modification

• autophosphorylation on a His residue

Effectors of protein activity

• LiaS kinase activity is inhibited by [protein|C107A958DFA2B0DA4837E2F9F648CD329A3116AC|LiaF], phosphatase acitivity is maintained by [protein|C107A958DFA2B0DA4837E2F9F648CD329A3116AC|LiaF] in the absence of the stress signal [Pubmed|23279150]

[SW|Localization]

• cell membrane (according to Swiss-Prot)
