Part:BBa_K3739010

LMT-his-GFP

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_K3739010 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 No part name specified with partinfo tag. to construct the expression system and obtained the composite part No part name specified with partinfo tag. and No part name specified with partinfo tag. to verify the function of our secretory peptides Aly01 and LMT.
