Frequently Asked Questions
What is genetic code expansion and how does Constructive.bio use it?
Genetic code expansion reassigns codons in an organism's genome so that the ribosome incorporates non-canonical amino acids (ncAAs) during translation. Constructive.bio uses whole-genome-recoded Syn61 E. coli with freed sense codons and engineered aminoacyl-tRNA synthetase/tRNA pairs to incorporate over 300 ncAAs site-specifically into peptides and proteins.
What is Syn61 and why is it important for peptide manufacturing?
Syn61 is Constructive.bio's whole-genome-recoded E. coli strain in which specific sense codons have been reassigned across all ~4 million base pairs. Unlike amber suppression, which competes with natural termination, Syn61 provides dedicated codons for ncAAs — enabling high-fidelity, multi-site incorporation without compromising cell viability or yield.
How many non-canonical amino acids can be incorporated into a single peptide?
Constructive.bio's platform can incorporate up to three different non-canonical amino acids in a single peptide, each at defined positions. This includes functional handles for click chemistry conjugation, backbone modifications for protease resistance, and lipophilic residues for half-life extension.
What is amber suppression and how does Constructive.bio's approach differ?
Amber suppression uses the UAG stop codon to encode a single ncAA, but competes with release factor 1 (RF1) for termination, limiting efficiency and restricting incorporation to one ncAA type. Constructive.bio reassigns sense codons in a fully recoded genome, eliminating competition and enabling multiple orthogonal ncAAs in one molecule at high fidelity.
What types of peptide therapeutics does the platform enable?
The platform supports nine therapeutic modalities: GLP-1 peptides, antibody-drug conjugates (ADCs), oral peptides, optimised peptides, interleukins and cytokines, VHH nanobodies, immunocytokines, covalent biologics, and vaccine conjugates. Each leverages ncAA incorporation for properties unachievable with the 20 natural amino acids.
