The organism we used in the lab E.coli (K12) DH5 alpha, could be pathogenicto human beings. lt may cause irritation to skin, eyes, and respiratorytract and affect kidneys.
The E.coli strain we used do have pathogenicity to human. But the relatively low pathogenicity, short life and vulnerability to environment factors ofthe used strain have limited the risk to general public.
The E.coli strains we used during the project are transformed with plasmids containing antibiotic markers The release of those transformed strains may cause problems like the leakage of resistance genes to wild bacterial flora.
The strains we used during our project do not contain hazardous genetic compartments. The risk through malicious misuse is quite low
The system we are trying to build is mainly meant for drug screening in pharmaceutical industry. The scale of production will always be limited.
No. But as the most used model organism in molecular biology, the risk of E.coli is relatively low.
Before the project started, we all received instructions concerning the safety problems, such as how to protect ourselves in the lab, how to handle the biological materials properly to lower the risk to public and environment.

The biosafety level of our lab is Categroy 1.
Risk Group 1.
Those questions are answered because we have parts originated from organisms from Risk Group 2. They are Listeria monocytogenes and Mycobacterium smegmatis.
Listeria monocytogenes
2
BBa_K1045003 Diadenylate cyclase domain of L. monocytogenes, DacA (CdaA, Lmo2120) We would like to look into diadenylate cyclase(DAC) of gram-positive pathogen, as potential target for novel antibiotics.
Cloned from purchased Listeria genome
We actually didn't work with Listeria monocytogenes. Our parts were cloned from purchased genome. And the parts themselves are not hazardous nor toxic since mammals and a few gram-negative bacteria don't use c-di-AMP as a signal molecule.
We follow strictly the S1 protocol to avoid any risks.
This part is non-hazardous nor toxic while mammals and gram-negative bacteria don't use c-di-AMP as a signal molecule. And this is the reason why c-di-AMP is a possible target for novel antibiotics
We would like to look into diadenylate cyclase(DAC) of gram-positive pathogen, as potential target for novel antibiotics. There are definitely DAC in less dangerous organism like B.substilis, but DAC from B.substilis is rather difficult to purify, and our final goal is to get a 3D structure.
No.

Mycobacterium smegmatis

BBa_K1045000 The operator DNA sequence that DarR binds, DarR operator
BBa_K1045001 Code regulatory protein DarR, which binds c-di-AMP
DarR is reported to be a transcriptional inhibitor in Mycobacterium smegmatis and c-di-AMP stimulates its binding to its operator sequence, acting as a co-inhibitor. (Zhang et al., 2012) We have built a reporter system of c-di-AMP based on that.
Cloned from purchased Mycobacteria genome
We actually didn't work with Mycrobacterium segmatic. Our parts were cloned from purchased genome. And the parts themselves are not hazardous nor toxic.
We follow strictly the S1 protocol to avoid any risks.
BBa_K1045000 is only a 14bp palindrome operator sequence.
BBa_K1045001 encodes a transcriptional inhibitor DarR. DarR has no catalytic function and is not toxic.
Because DarR is the very recently discovered regulatory protein which responds to c-di-AMP.There is no another protein in a less dangerous organism discovered yet.
No.
