J23100-B0030-Aly01-his-GFP-B0010

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 Aly01.We use BBa_K3739038 to construct the expression system and help prove the function of some signal peptide. Aly01 is a signal peptide from the alginate lyase of V.natriegens and GFP can show the secretion effciency of Aly01

Biology

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.

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_K3739038 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 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.
