MAPK phosphothreonine lyase

UniProtKB accession:  P0A2M9

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Secreted effector that irreversibly inactivates host MAP kinases by catalyzing the dephosphorylation of the phosphothreonine residue in the pT-X-pY motif in MAPK2/ERK2, MAPK3/ERK1, and p38, via a beta-elimination reaction leading to a dehydrobutyrine residue. Is also able to remove the phosphate group from phospho-JNK in vitro, but JNK may not be a substrate in vivo. Could help suppress localized pro-inflammatory responses at infection foci in the spleen and liver, and thereby facilitate bacterial growth.
