About the Project

This project aims to apply synthetic biology and metabolic engineering strategies to one of the most complex biochemical pathways found in nature in order to address a current need for a cheaper and more reliable source of vitamin B12, the so-called anti-pernicious anaemia factor. Vitamin B12 is a cobalt-containing molecule that acts as a coenzyme and cofactor for a number of key biological processes. It is unique among the vitamins in that it is made solely by prokaryotes but is retained by many eukaryotes as a nutrient because of the greatly improved rates of reaction observed with B12-dependent enzymes in comparison to B12-independent processes. Vitamin B12 is a structurally complex molecule and this is reflected in an equally complex biochemical pathway. Our research group at QIB have worked for many years on the biochemistry of the pathway and are recognised for their many contributions to this area. BASF are pioneers in the area of commodity and speciality chemicals and are market leaders in vitamin production. This joint project between the Warren lab and BASF therefore presents an opportunity to provide new key fundamental insights into the operations of the B12 biosynthetic pathway and at the same time lead to the construction of a strong B12-overproduction strain. 

The Norwich Research Park Biosciences Doctoral Training Partnership (NRPDTP) is open to UK and international candidates for entry October 2021 and offers postgraduates the opportunity to undertake a 4-year PhD research project whilst enhancing professional development and research skills through a comprehensive training programme. You will join a vibrant community of world-leading researchers. All NRPDTP CASE students undertake a three to 18-month placement with the non-academic partner during their study. The placement offers experience designed to enhance professional development. Students with, or expecting to attain, at least an upper second class honours degree, or equivalent, are invited to apply.

This project has been shortlisted for funding by the NRPDTP. Shortlisted applicants will be interviewed on Tuesday 25th January, Wednesday 26th January and Thursday 27th January 2022.

Visit our website for further information on eligibility and how to apply: https://biodtp.norwichresearchpark.ac.uk/

Our partners value diverse and inclusive work environments that are positive and supportive. Students are selected for admission without regard to gender, marital or civil partnership status, disability, race, nationality, ethnic origin, religion or belief, sexual orientation, age or social background.


Funding Notes

This project is awarded with a 4-year Norwich Research Park Biosciences Doctoral Training Partnership (NRPDTP) PhD CASE studentship. The studentship includes payment of tuition fees (directly to the University), a stipend for each year of the studentship (2021/22 stipend rate: £15,609) plus a CASE Partner stipend enhancement of £2,000 p.a., and a Research Training Support Grant for each year of the studentship of £5,000 p.a. plus a CASE Partner RTSG contribution of £1,500 p.a.
