Prof Mike Merrick

Project Leader
Molecular Microbiology

I retired from full-time research in February 2012 and now my primary role at JIC is as Chair of the Norwich Research Park Doctoral Training Partnership.

Throughout my research career my interests have focussed on bacterial nitrogen metabolism and the ways in which bacteria control all aspects of that metabolism in response to the availability of fixed nitrogen (for reviews see: Arcondeguy et al, 2001; Huergo et al, 2013).

Over the last decade, the major research in my lab concerned the biology of the ubiquitous ammonium transport (Amt) proteins and of the signal transduction proteins of the PII family. Ammonium transport (Amt) proteins are found in eubacteria, archaebacteria, fungi, plants, and lower animals. Members of the Amt family are also present in higher animals including humans where their homologues are the Rhesus (Rh) proteins. A detailed discussion of these topics can be found on my personal web pages.
