Cyclization of the peptide backbone by connecting the N- and C-terminus can endow target peptides with favorable properties, such as increased stability or potential oral bioavailability. However, there are few tools available for carrying out this modification. Asparaginyl endopeptidases (AEPs) are
OBJECTIVE
The cyclotide kalata B1 is found in the leaves of Oldenlandia affinis and is a potent insecticidal and nematocidal molecule. This peptide is cleaved from a precursor protein, Oak1, and ligation of the N- and C-termini occurs to form a continuous peptide backbone. The subcellular location
Chemical and bio-conjugation techniques have been developed rapidly in recent years and allow the building of protein polymers. However, a controlled protein polymerization process is always a challenge. Here, we have developed an enzymatic methodology for constructing polymerized protein step by
The recent development of chemical and bio-conjugation techniques allows for the engineering of various protein polymers. However, most of the polymerization process is difficult to control. To meet this challenge, we develop an enzymatic procedure to build polyprotein using the combination of a
Plant cyclotides are a large family of naturally occurring circular proteins that are produced from linear precursors containing one, two or three cyclotide domains. The mechanism of excision of the cyclotide domains and ligation of the free N- and C-termini to produce the circular peptides has not
