Editing Beta sheet (section)

== Structural architectures of proteins with β-sheets ==
β-sheets are present in [[All-β proteins|all-β]], [[Α+β proteins|α+β]] and [[Α/β proteins|α/β]] domains, and in many [[peptide]]s or small proteins with poorly defined overall architecture.<ref>{{cite journal | vauthors = Hubbard TJ, Murzin AG, Brenner SE, Chothia C | title = SCOP: a structural classification of proteins database | journal = Nucleic Acids Research | volume = 25 | issue = 1 | pages = 236–9 | date = January 1997 | pmid = 9016544 | pmc = 146380 | doi = 10.1093/nar/25.1.236 }}</ref><ref>{{cite journal | vauthors = Fox NK, Brenner SE, Chandonia JM | title = SCOPe: Structural Classification of Proteins--extended, integrating SCOP and ASTRAL data and classification of new structures | journal = Nucleic Acids Research | volume = 42 | issue = Database issue | pages = D304-9 | date = January 2014 | pmid = 24304899 | doi = 10.1093/nar/gkt1240 | pmc=3965108}}</ref> [[All-β proteins|All-β domains]] may form [[beta barrel|β-barrels]], [[β-sandwich]]es, β-prisms, [[Beta-propeller domain|β-propellers]], and [[Beta helix|β-helices]].
