Peroxynitrite, formed from the reaction between nitric oxide and superoxide, and produced in plants during the hypersensitive response is able to nitrate specifically AtMKK4, whereas AtMKK4 closest homolog AtMKK5 is insensitive to peroxyntirite treatment. This suggests that both proteins can achieve unique functions in presence of nitrating agents, in particular in response to pathogen attacks.

Peroxynitrite produced during the hypersensitive response could question the functional redundancy of AtMKK4 and AtMKK5 via selective nitration.

Abstract

Peroxynitrite, formed from the reaction between nitric oxide and superoxide, and produced in plants during the hypersensitive response is able to nitrate specifically AtMKK4, whereas AtMKK4 closest homolog AtMKK5 is insensitive to peroxyntirite treatment. This suggests that both proteins can achieve unique functions in presence of nitrating agents, in particular in response to pathogen attacks.
