== Function ==
-
 
+
[https://www.uniprot.org/uniprot/CAPSD_AMVYS CAPSD_AMVYS] Capsid protein. Binds to the to the 3' end of the nonpolyadenylated viral RNA and is involved in viral RNA translation initiation. Probably binds RNA and plays a role in packaging (By similarity).

==Overview==
+
</StructureSection>
-
Alfalfa mosaic virus genomic RNAs are infectious only when the viral coat protein binds to the RNA 3' termini. The crystal structure of an alfalfa mosaic virus RNA-peptide complex reveals that conserved AUGC repeats and Pro-Thr-x-Arg-Ser-x-x-Tyr coat protein amino acids cofold upon interacting. Alternating AUGC residues have opposite orientation, and they base pair in different adjacent duplexes. Localized RNA backbone reversals stabilized by arginine-guanine interactions place the adenosines and guanines in reverse order in the duplex. The results suggest that a uniform, organized 3' conformation, similar to that found on viral RNAs with transfer RNA-like ends, may be essential for replication.
