The <scene name='48/484916/Starting_molecule/3'>leader protein</scene> (Lpro)from FMDV is a cysteine protease and constitutes a virulent factor during FMDV infection. It is the first protein that is translated from the growing polyprotein and upon translation frees itself by self cleavage. This self-processing event is believed to occurred intramolecularly due to the presence of a flexible <scene name='User:Gisselle_Medina/Sandbox7_Leader/C_terminal_extension/2'>C-terminal extension</scene> CTE is composed of 18 amino acid residues and presumably can fold back into its own <scene name='User:Gisselle_Medina/Sandbox7_Leader/Active_site_mutated/1'>active site</scene>. Lpro is produced in two forms, named Lab and Lb, due to the initiation of protein synthesis at two AUG located 84 nucleotides apart. | The <scene name='48/484916/Starting_molecule/3'>leader protein</scene> (Lpro)from FMDV is a cysteine protease and constitutes a virulent factor during FMDV infection.
