L-peptidase explained

L-peptidase
Ec Number:3.4.22.46

L-peptidase is an enzyme.[1] [2] This enzyme catalyses the following chemical reaction

Autocatalytically cleaves itself from the polyprotein of the foot-and-mouth disease virus by hydrolysis of a Lys-Gly bond. Subsequently, it cleaves host cell initiation factor eIF-4G at bonds -Gly-Arg- and -Lys-Arg-

This enzyme is coded bz foot-and-mouth disease virus.
