{"amyloid_non_amyloid": "Amyloid", "description": "[YVVFV fibril structure] The peptides YVVFL form oligomers and amyloid-like fibrils. YVVFV shows an early stage oligomer distribution similar to those of the previous two, but amyloid-like aggregates are less abundant. Atomic resolution X-ray structures of YVVFV show two different modes of interactions at the dry interface between steric zippers and pairs of antiparallel Beta-sheets, but both are less favorable than the packing motif found in YVVFL. Both YVVFV and YVVFL can form a Class 6 steric zipper. However, in YVVFV, the strands between mating sheets are parallel to each other and in YVVFL they are antiparallel.
