DescriptionLard 1 was designed for the secretion of fusion proteins.The LARD 1 included four glycine-rich repeats comprising a β-roll structure, and were added to the C-terminus of test proteins. Either Pro-Gly linker or Factor Xa site can be added between fusion proteins and LARD 1. Upon supplementation of E. coli with ABC transporter from E. chrysanthemi (ABC transporter PrtDEF), which function well in the phylogenetically-neighboring genus E.coli, EGF-LARDs were excreted into the culture supernatant.
NotesIn our designed LARD 1, we favoured not to add these cleavage site so if you want, yo can add either Pro-Gly linker or Factor Xa site. Secretion of fusion proteins with LARDs could be detected by Western blotting. Fusion proteins were traced in the culture supernatant using antibody against LARDs. Polyclonal antibodies against the C-terminal signal sequence were produced with a synthetic peptide (YQPTDRLVFQGADGST, residues 421???436 of TliA ,also of LARD).
SourceLARD 1 composed of residues 303-476 of thermostable lipase (TliA) of Pseudomonas fluorescens.
