Dr Mueller is interested in enzyme-catalysed reactions that modulate hormone function and act as biological switches. One of these transformations is the dynamic sulfation and de-sulfation of steroid hormones. Dr Mueller’s research group studies these sulfation pathways, using a variety of biochemical, bioanalytical and cell biological techniques.

Jon has authored more than 25 primary research and review papers. His lab received funding from the European Commission (Marie Curie fellowship SUPA-HD 625451 and Erasmus actions), the Wellcome Trust (ISSF), the MRC (Proximity-to-Discovery) as well as the Society for Endocrinology.

Dr Mueller is passionate about Higher Education in endocrinology and pharmacology. He also is a BioMed and MPharm Tutor and a Mentor in the LGBT mentoring programme from the University’s Career’s Network. Jon is the recipient of the Outstanding Teaching Award for all MDS, awarded by the Guild of Students and the Vice Chancellor, both in 2019 and in 2020.

Jon runs several conferences around sulfation pathways – the next one planned for September 2021 in Sevilla, Spain. Further outreach and public engagement include the university’s Masterclasses programme for A level students, Marie Curie grant writing and training events as well as gender and diversity presentations.

In collaboration with a Birmingham-based artist, Jon has created conference posters and journal cover art. This collaboration was presented at the university’s Worlds collide seminar series. Jon also has presented photography-based digital artwork at the Barber Institute of Fine Arts at Recovery Art exhibitions.

  • Fellow of the Higher Education Academy (FHEA), Beacon Programme, University of Birmingham, 2019
  • Distinguished visiting fellow at the Krupp Institute for Advanced Studies, Greifswald, Germany, 2015
  • Habilitation (DSc equivalent) in Biochemistry and Molecular Biology, University of Duisburg and Essen, Germany, 2012
  • PhD in Biochemistry, University of Halle and Wittenberg, Germany, 2004
  • Biochemistry diploma (MA equivalent, With Honours), University of Halle and Wittenberg, Germany, 2001


A protein biochemist by training, Dr Mueller earned his PhD at Max Planck Institute Dortmund working with Peter Bayer. He then moved for post-doctoral and senior post-doc experience to the University of Duisburg and Essen, still working with Peter.

Jon’s interest in sulfation pathways was sparked by two EMBO visiting research fellowships, 2007 and 2011, with Annalisa Pastore at the MRC National Institute for Medical Research in London, which is now part of the Crick Research Institute.

In 2012, Jon moved to Birmingham as a Marie Curie Senior Research Fellow to work on the sulfation of steroid hormones with Wiebke Arlt. Here in Birmingham, Jon now is Lecturer in Endocrine Biochemistry at the Institute of Metabolism and Systems Research.

Postgraduate supervision

Dr Mueller welcomes diversity in his group. He is always interested in getting in touch with young scientists who are interested in the group’s research activities. Please get in touch if you plan a lab placement or like to join the lab as a PhD or a postdoc.


Dr Mueller’s research into sulfation pathways is strongly informed by studying patients with genetic defects in different components of the sulfation machinery. In this way he realised that loss-of-function of the sulfation enzyme PAPSS2 cannot be compensated by the related enzyme PAPSS1 (JCEM 2015; 100(4): E672-80). Recently they could provide a molecular explanation for this finding: They reported a novel protein interaction between PAPSS2 and the sulfotransferase SULT2A1 (Mueller et al, JBC 2018; 293(25): 9724-35). On these grounds, Dr Mueller postulated that sulfate activation by PAPS synthases is an additional layer of regulation in sulfation pathways.

PAPS synthases have been the group’s research focus for many years. Ground-breaking work was the first biophysical characterisation of these enzymes (JBC 2012; 287(21): 17645-55) that identified PAPSS2 as marginally stable protein. Jon has reviewed recent concepts of protein stability in light of these findings (Front Mol Biosci. 2019; 6:31). It will be exciting to see how stability and other biophysical properties of this important protein differ, when studied within the living cell compared to when using recombinant protein.

Structure and function of sulfation enzymes not only from humans, but also from other organisms are of interest to the group. Jon contributed to a study analysing the redox regulation of the plant PAP phosphatase Sal1 (PNAS 2016; 113(31): E4567-76) and the structural elucidation of the plant sulfotransferase SOT18 (Sci Rep. 2017; 7(1): 4160). Clear evidence how insightful it can be to “look over the fence” of one’s own speciality.
