SpyTag and SpyCatcher are able to form isopeptide bond with the other without any assistant, Aly01 is a signal peptide for secretion, LecA is a sugar binding protein.
Biology
SpyTag
SpyTag (a 13-residue peptide) and SpyCatcher (a 116-residue domain) are engineered split fragments of the second immunoglobulin-like collagen adhesin domain (CnaB2) of the fibronectin-binding protein (FbaB) of Streptococcus pyogenes. IGEM team Peking 2016 has modified the peptide and domain into triple SpyTag and triple SpyCatcher, which can form bonds with each other and create Spy Crosslinking Network, enabling the formation of hyper-branched products and polymer network at low concentrations, and gels with a high degree of cross-linkage at high concentrations.1
LecA
LecA is a soluble galactose-binding lectin from bacterium Pseudomonas aeruginosa. The lectin is specific for α-galactose.2
Aly01
Aly01 is alginate lyase from Vibrio natriegens SK42.001, which is secreted out and able to digest alginate to unsaturated alginate oligosaccharide. Its signal peptide (named Aly01 in our parts), which is fused with heterogenous protein, is performed well in E. coli. It is implied that the heterogenous protein fused with Aly01 signal peptide may be also secreted efficiently.
Usage
In order to get secreted 3SpyTag-LecA and further purify it, we added the signal peptide Aly01, followed by a his-tag (6*His) at the N-terminal of 3SpyTag-LecA. We used both Status: 500 Content-type: text/html

and BBa_K3739115, which are assembled on the expression vector pET-28a(+) by standard assembly. The constructed plasmids were transformed into Vibrio natriegens, then the positive transformants were selected by kanamycin and confirmed by colony PCR and sequencing.
Characterization
1. Agarose Gel Electrophoresis
When we were transferring the plasmid into Vibrio natriegens, colony PCR was used to certify the plasmid was correct. We got the target (1154bp).
