Mutations of key substrate binding residues of leishmanial peptidase T alter its functional and structural dynamics.

Saleem Yousuf Bhat | Insaf Ahmed Qureshi
Biochimica et biophysica acta. General subjects | 2020

M20 aminopeptidases, such as Peptidase T (PepT), are implicated in the hydrolysis of oligopeptides during the terminal stages of protein degradation pathway to maintain turnover. Therefore, specific inhibition of PepT bores well for the development of novel next-generation antileishmanials. This work describes the metal dependence, substrate preferences and inhibition of PepT, and demonstrates in detail the role of its two conserved substrate binding residues.
