Protein engineers often need to do in-frame assemblies in order to assemble together different signal sequences, proteins domains, and protein tags. BioBrick™ standard assembly is not well-designed for this task because the scar sequence formed by the SpeI-XbaI ligation is 8 base pairs long. As a result, different groups have developed modified or alternative assembly schemes to facilitate assembly of protein domains.
Pam Silver's lab has developed the Silver lab standard for assembling protein domains. It relies on shortening the BioBrick prefix and suffix each by 1 base pair such that the resulting SpeI-XbaI scar is only 6 base pairs long and protein domains can be assembled in frame.
