Call for applications: SWBio DTP PhD studentship: "Enantioselective
polyketide biocatalysis through simulation-led redesign"

Supervisors: Dr Marc van der Kamp, School of Biochemistry and Prof Matthew
Crump, School of Chemistry, University of Bristol.
Additional supervisory team: Dr Paul Race, School of Biochemistry and Prof
Chris Willis, School of Chemistry.

We are looking for outstanding students with a passion for research at the
interface of chemistry and biology for a fully funded 4-year SWBio PhD
studentship (fees and stipend at the standard rate). The project is
available from September 2018 for candidates that satisfy BBSRC & SWBio DTP
studentship eligibility requirements (see
*https://www.swbio.ac.uk/programme/eligibility/
<https://www.swbio.ac.uk/programme/eligibility/>* if you are unsure).

Our laboratories have a long-standing interest in the use of
computational, biophysical
and chemical methods to understand and manipulate biosynthesis. For this
project, the aim is to develop ways to control how polyketide synthases, an
important class of natural biocatalytic machinery, set the stereochemistry
of their products, polyketides, many of which have antibiotic and/or
anticancer activities. This will be done by modifying – or redesigning – a
key enzyme in polyketide synthase systems that sets stereochemistry in the
polyketide product chain, a ketoreductase. In particular, in the so-called
polyketide synthase type II systems, an acyl-carrier protein (ACP) will
bring the evolving polyketide chain to a ketoreductase, which will
subsequently set a stereochemical center. Existing structural information
defines how the ACP and the ketoreductase involved in making the polyketide
actinorhodin (a natural antibiotic) will guide the development of
computational prediction protocols. This will be the bulk of the work,
involving QM/MM reaction simulations, molecular dynamics and
protein-protein docking. The simulations will predict new ketoreductase
variants that alter the stereochemical outcome. To test and improve these
computational predictions, experimental characterisation of promising
enzyme variants (product outcome, kinetics and structural biology) will be
performed. Once successful, the atomic detail of new variants will be
confirmed through structural biology techniques (NMR, X-ray
crystallography).
This interdisciplinary project is thus combining the expertise in
computational simulation of enzymes in Bristol and the expertise from an
internationally leading academic team with multidisciplinary expertise of
polyketide systems and the relevant experimental techniques (enzymology,
molecular biology, chemistry and structural biology).
The student will benefit from access to the recently upgraded BlueCrystal
High-Performance Computing cluster in Bristol (~800 TFLOPS), as well as a
vibrant collaborative environment with excellent computational chemistry
and experimental groups in Bristol and beyond.

The ideal applicant will have a strong academic record, a BSc or MChem/MSc
degree in Chemistry, Biochemistry or related fields, and some previous
research experience in structural, chemical or computational chemistry/biology.
The ideal candidate will also demonstrate keen interest in the use of
computer simulation to gain understanding of biomolecular interaction and
enzymes and enthusiasm for multidisciplinary research.

To apply, please send initially a cover letter and CV to
[log in to unmask] Informal enquiries are encouraged as
soon as possible.
Shortlisted candidates will be invited to apply formally to the SWBio DTP.
Candidates should make initial contact by November 30th 2017 at the latest
(formal application is due on December 4th).
