- In chlorophyll biosynthesis, insertion of Mg2+ into protoporphyrin IX is catalysed in an ATP-dependent reaction by a three-subunit (BchI, BchD and BchH) enzyme magnesium chelatase. In this work we present the three-dimensional structure of the ATP-binding subunit BchI. The structure has been solved by the multiple wavelength anomalous dispersion method and refined at 2.1 A resolution to the crystallographic R-factor of 22.2 % (Rfree = 24.5 %). It belongs to the chaperone-like ''ATPase associated with a variety of cellular activities'' (AAA) family of ATPases, with a novel arrangement of domains: the C-terminal helical domain is located behind the nucleotide-binding site, while in other known AAA module structures it is located on the top. Examination by electron microscopy of BchI solutions in the presence of ATP demonstrated that BchI, like other AAA proteins, forms oligomeric ring structures. Analysis of the amino acid sequence of subunit BchD revealed an AAA module at the N-terminal portion of the sequence and an integrin I domain at the C terminus. An acidic, proline-rich region linking these two domains is suggested to contribute to the association of BchI and BchD by binding to a positively charged cleft at the surface of the nucleotide-binding domain of BchI. Analysis of the amino acid sequences of BchI and BchH revealed integrin I domain-binding sequence motifs. These are proposed to bind the integrin I domain of BchD during the functional cycle of magnesium chelatase, linking porphyrin metallation by BchH to ATP hydrolysis by BchI. An integrin I domain and an acidic and proline-rich region have been identified in subunit CobT of cobalt chelatase, clearly demonstrating its homology to BchD. These findings, for the first time, provide an insight into the subunit organisation of magnesium chelatase and the homologous colbalt chelatase.

The RD-Connect Genome-Phenome Analysis Platform : Accelerating diagnosis, research, and gene discovery for rare diseases
- 2022

- Rare disease patients are more likely to receive a rapid molecular diagnosis nowadays thanks to the wide adoption of next-generation sequencing. However, many cases remain undiagnosed even after exome or genome analysis, because the methods used missed the molecular cause in a known gene, or a novel causative gene could not be identified and/or confirmed. To address these challenges, the RD-Connect Genome-Phenome Analysis Platform (GPAP) facilitates the collation, discovery, sharing, and analysis of standardized genome-phenome data within a collaborative environment. Authorized clinicians and researchers submit pseudonymised phenotypic profiles encoded using the Human Phenotype Ontology, and raw genomic data which is processed through a standardized pipeline. After an optional embargo period, the data are shared with other platform users, with the objective that similar cases in the system and queries from peers may help diagnose the case. Additionally, the platform enables bidirectional discovery of similar cases in other databases from the Matchmaker Exchange network. To facilitate genome-phenome analysis and interpretation by clinical researchers, the RD-Connect GPAP provides a powerful user-friendly interface and leverages tens of information sources. As a result, the resource has already helped diagnose hundreds of rare disease patients and discover new disease causing genes.

Chelatases: distort to select?
- 2006

- Chelatases catalyze the insertion of a specific metal ion into porphyrins, a key step in the synthesis of metalated tetrapyrroles that are essential for many cellular processes. Despite apparent common structural features among chelatases, no general reaction mechanism accounting for metal ion specificity has been established. We propose that chelatase-induced distortion of the porphyrin substrate not only enhances the reaction rate by decreasing the activation energy of the reaction but also modulates which divalent metal ion is incorporated into the porphyrin ring. We evaluate the recently recognized interaction between ferrochelatase and frataxin as a way to regulate iron delivery to ferrochelatase, and thus iron and heme metabolism. We postulate that the ferrochelatase-frataxin interaction controls the type of metal ion that is delivered to ferrochelatase.

Beyond the Individual : Sources of Attitudes Towards Rule Violation in Sport
- 2012

Tidskriftsartikel (refereegranskat)abstract
- Today, certain rule-violating behaviours, such as doping, are considered to be an issue of concern for the sport community. This paper underlines and examines the affective dimensions involved in moral responses to, and attitudes towards, rule-violating behaviours in sport. The key role played by affective processes underlying individual-level moral judgement has already been implicated by recent developments in moral psychological theories, and by neurophysiological studies. However, we propose and discuss the possibility of affective processes operating on a social level which may influence athletes’ individual-level attitudes. We conclude that one-sided focus on individual rule- violating behaviour and individual sanctions may prove to be ineffective in coming to terms with the issue. In this regard we recommend a twofold approach by addressing underlying social dimensions, along with preventive measures through affect-oriented education.

Cheating is the name of the game : Conventional cheating arguments fail to articulate moral responses to doping
- 2013

Tidskriftsartikel (refereegranskat)abstract
- One of the most common arguments in the discussion on doping is that it represents a form of cheating. In this paper, it is argued that common doping-is-cheating arguments based on notions of rule-violation and unfair advantage are inadequate, since they treat cheating as distinct from the structure and the logic of competitive sport. An alternative approach to cheating in sport as regards performance enhancement will be offered based on the ethics of participation in interpersonal relationships. This participatory perspective points towards the need to broaden our conception of agency and moral responsibility in relation to doping, beyond the notion of the individual “drug-cheat” who acts in a vacuum.
