Assembly standard 21/Overview
Researchers at UC Berkeley have developed the BglBrick assembly standard, or Assembly standard 21, based on idempotent assembly with BamHI and BglII restriction enzymes. In a nutshell, most parts look like this:
Prefix Suffix 5' GAATTC atg AGATCT ...part... GGATCC taa CTCGAG 3' EcoRI BglII BamHI * XhoI
Fusing two parts leaves the following scar:
5' [part A] GGATCT [part B] 3' G S
Note, however, that Assembly standard 20 is intended as a minimal physical assembly standard, and only those features needed for interconversion of BglBrick assembly standard plasmids are formally defined. Therefore, atg
and taa
spacers are not core definitions of the standard.
