Translation directed by several picornavirus IRES elements can usually take place after cleavage of eIF4G by picornavirus proteases 2A(pro) or L(pro). The hepatitis A virus (HAV) IRES is thought to be an exception to this rule because it requires intact eIF4F complex for translation. In line with previous results we report that poliovirus (PV) 2A(pro)(More)
Translation of foot-and-mouth disease virus RNA initiates at one of two start codons leading to the synthesis of two forms of leader proteinase L(pro) (Lab(pro) and Lb(pro)). These forms free themselves from the viral polyprotein by intra- and intermolecular self-processing and subsequently cleave the cellular eukaryotic initiation factor (eIF) 4 G. During(More)
The foot-and-mouth disease virus leader proteinase (Lb(pro)) cleaves itself off the nascent viral polyprotein. NMR studies on the monomeric variant Lb(pro) L200F provide structural evidence for intramolecular self-processing. (15)N-HSQC measurements of Lb(pro) L200F showed specifically shifted backbone signals in the active and substrate binding sites(More)
