BioBrick mdnED

Part name: BBa_K627000
Part type: Coding
Short description: ABC transporter and N-acetyltransferase from the mdn-cluster

Full description:
The BioBrick mdnED is a part of the whole microviridin gene (mdn) cluster, which encodes the protease inhibitor microviridin L. Microviridins are tricyclic depsipeptides, which are ribosomally synthesized by the cyanobacteria Microcystis aeruginosa (Ziemert et al., 2010). They have a promising potential for therapy as they can block disease-relevant proteases (Ziemert et al., 2008).

Microviridins are synthesized from a ribosomal precursor peptide (MdnA). Additionally, the microviridin L biosynthesis gene cluster consists of genes encoding an ATP-grasp-type ligase (mdnB and mdnC) and genes, which encode an ABC transporter (mdnE) and a N-acetyltransferase of the GNAT family (mdnD) (Ziemert et al., 2008).

In the following BioBrick mdnED the genes mdnD (N-acetyltransferase of the GNAT family) and mdnE (ABC transporter) is encoded (Ziemert et al., 2008).

Source of the part:
The BioBrick mdnDE as a part of the microviridin gene (mdn) cluster was isolated from Microcystis aeruginosa strain NIES-843.

Design information:
This BioBrick was built by PCR using the following PCR primers
Forward primer: TAAATGAATTCGCGGCCGCTTCTAGATGCCTCAATATACTACTAAAC
Reverse primer: ATTTCTGCAGCGGCCGCTACTAGTATCAGCAAACCCTACTTAATTTC
To insert mdnED in the vector pSB1C3, the resulting PCR product and the vector were digested with the restriction enzymes, EcoRI and SpeI.

Because this BioBrick is an expression part, the adenin of mdnE gene's start codon is part of the XbaI recognition site.

BioBrick mdnA c-myc gene III

Part name: BBa_K627006
Part type: Coding
Short description: Fusion part of mdnA gene with c-terminal myc-tag and gene III

Full description:
An appropriate vector containing the biobrick mdnA-myc-geneIII-fusion gene is a very important milestone of the development of a functional phage display system for screening of a microviridin (mdnA) library. Microviridins are tricyclic peptides from cyanocacteria which are able to bind and inhibit proteases. The gene III protein is a coat protein from the filamentous bacteriophage M13. It appears only 3-5 times on the tip of the phage and is responsible for infection of bacterial cells. After transformation of E. coli with the vector and co-infection with helper phages E. coli cells are able to produce phage particles carrying microviridin on their surface. Using these phages the fundamental suitability of phage display as a screening method for mdnA varieties was indicated. This has great importance for identifying microviridin varieties of therapeutical relevance. The inserted myc sequence enables the easy detection or purification . In our project the successful expression of the mdnA-myc -gene-III-fusion protein was determined by ELISA. Subsequent the production of phages carrying mdnA in E. coli was analyzed by phage display.

Source of the part:
The BioBrick mdnA is a part of the microviridin gene (mdn) cluster which was isolated from Microcystis aeruginosa strain NIES-843.
The gene III protein is a coat protein from the filamentous bacteriophage M13.

Design information:
Gene III was amplified from the vector pak100 bla KDIR using the following primer
Forward:TAAGCTTCTAGATGGCCGGCGAGCAGAAGCTGATCTCTGAGGAAGACCTGGGTGGTGGCTCTGGTTCC
Reverse: TGCTTAGACGTCCTGCAGCGGCCGCTACTAGTATTAACCGGTAGACTCCTTATTACGCAGTA

The mdnA gene was amplified from the vector pARW089 using the following primer
Forward: TTCCATGGCGCCAGAGGAATCTAGATGGCATATCCCAACGATC
Reverse: CTTCTGACTGGGAAGATTATACCGGTTAATACTAGTAGCGGCCGCTGCAGGACGTC

Gene III was amplified from pak100blaKDIR and mdnA from pARW089 by PCR. The primers were designed to enable the introduction of iGEM. The PCR product gene III was digested by whereas the PCR product mdnA was digested by AgeI. Thus a mdnA-gene III fusion part according to RFC25 was generated whereby AgeI and NgoMIV overhangs are compatible and placed in frame with the protein sequence. The ligation of AgeI and NgoMIV overhangs resulted in a scar coding for the threonine and glycine. Because the introduction of restriction sites before mdnA leaded to a great distance between ribosome binding site and mdnA a second RBS was inserted among SfoI and XbaI recognition sites to ensure a sufficiently expression rate of the mdnA-geneIII-fusion gene. Between mdnA and gene III myc sequence was inserted.

Because this BioBrick is an expression part, the adenin of mdnA gene start codon is part of the XbaI recognition site. Further the sequence contains a AgeI recognition site after gene III.

BioBrick AraC_TEV

Part name: BBa_K627008
Part type: Composite Part
Short description: Fusion part of pBAD arabinose-inducible induction system and the TEV protease

Full description:
This BioBrick is a 2 parts fusion of pBAD arabinose-inducible induction system and the TEV protease. TEV protease is the common name for the 27 kDa catalytic domain of the Nuclear Inclusion a endopeptidase (NIa) encoded by the tobacco etch virus (TEV). TEV protease is a useful reagent for cleaving fusion proteins. It recognizes a linear epitope of the general form E-Xaa-Xaa-Y -Xaa-Q-(G/S), with cleavage occurring between Q and G or Q and S. In TEV protease the serine nucleophile of the conventional Ser-Asp-His triad is a cysteine instead. This probably explains why TEV protease is resistant to many commonly used protease inhibitors. At 37°C, the TEV protease forms inculsion body, which leads to an inactive form. Incubated at 30 °C, the protease is expressed as soluble type and is highly active. The induction system was amplified via PCR und fused via NgoMIV with the protease.
