LMT is a signal peptide from the lytic murein transglycosylase of V.natriegens and GFP can show the secretion effciency of LMT
This part contains a Vibrio natriegens-optimized GFP coding sequence, and the GFP is fused at N-terminal with his-tag in order to let us purify the protein. His-GFP is fused with secretory peptide from LMT.We use BBa_Kxxxx to construct the expression system and help prove the function of some signal peptide.
Biology
LMT
Lytic murein transglycosylase (LMT) is an enzyme which is able to degrade murein, a component of cell wall of bacteria. There are two kind of LMTs existing in E.coli: the membrane-binding one and the soluble one. The gene coding LMT homolog is also incorporated in the genome of Vibrio natriegens. The LMT signal peptide (named LMT in our parts) is from the LMT homolog, which can lead the fused protein secreted out of Vibrio natriegens.
GFP
Protein tags are peptides genetically fused to the proteins of interest. There are many different kinds of tags developed for for different purposes. For labeling experiments, normally the proteins of interest are tagged directly by fluorescent tags. Green fluorescent protein (GFP) make it easier to study protein localization, interactions and dynamics when fusing with other peptides and proteins.
Usage
Here, we used BBa_Kxxxx to construct the expression system and obtained the composite part BBa_Kxxxx. We transformed the constructed plasmid on the expression vector pET-28a (+) into V. natriegens to extract the protein. This protein work together with those from BBa_Kxxxx and BBa_Kxxxx to verify the function of our secretory peptides Aly01 and LMT.
