Structural and biochemical characterization of Malaria parasites
(Doctoral thesis, 2021-09-17)The Apicomplexa phylum includes more than 6000 species, and some of them are pathogens of humans and animals of socio-economic importance. The most representative parasites are Plasmodium spp. and Toxoplasma gondii. ... -
Structural and biophysical characterization of transcription factor HNF-1A as a tool to study MODY3 diabetes variants
(Journal article; Peer reviewed, 2022)Hepatocyte nuclear factor 1A (HNF-1A) is a transcription factor expressed in several embryonic and adult tissues, modulating the expression of numerous target genes. Pathogenic variants in the HNF1A gene are known to cause ... -
Structural and thermodynamic insight into phenylalanine hydroxylase from the human pathogen Legionella pneumophila
(Peer reviewed; Journal article, 2013-08-19)Phenylalanine hydroxylase from Legionella pneumophila (lpPAH) has a major functional role in the synthesis of the pigment pyomelanin, which is a potential virulence factor. We present here the crystal structure of lpPAH, ... -
Structural aspects of nucleotide ligand binding by a bacterial 2H phosphoesterase
(Peer reviewed; Journal article, 2017-01-31)The 2H phosphoesterase family contains enzymes with two His-X-Ser/Thr motifs in the active site. 2H enzymes are found in all kingdoms of life, sharing little sequence identity despite the conserved overall fold and active ... -
Structural insights into Charcot–Marie–Tooth disease-linked mutations in human GDAP1
(Journal article; Peer reviewed, 2022)Charcot–Marie–Tooth disease (CMT) is the most common inherited peripheral polyneuropathy in humans, and its different subtypes are linked to mutations in dozens of different genes. Mutations in ganglioside-induced ... -
Structural mechanism for tyrosine hydroxylase inhibition by dopamine and reactivation by Ser40 phosphorylation
(Journal article; Peer reviewed, 2022)Tyrosine hydroxylase (TH) catalyzes the rate-limiting step in the biosynthesis of dopamine (DA) and other catecholamines, and its dysfunction leads to DA deficiency and parkinsonisms. Inhibition by catecholamines and ... -
Structural properties and peptide ligand binding of the capsid homology domains of human Arc
(Journal article; Peer reviewed, 2021)The activity-regulated cytoskeleton-associated protein (Arc) is important for synaptic plasticity and the normal function of the brain. Arc interacts with neuronal postsynaptic proteins, but the mechanistic details of its ... -
Structural similarities and functional differences clarify evolutionary relationships between tRNA healing enzymes and the myelin enzyme CNPase
(Peer reviewed; Journal article, 2017-05-16)Background: Eukaryotic tRNA splicing is an essential process in the transformation of a primary tRNA transcript into a mature functional tRNA molecule. 5′-phosphate ligation involves two steps: a healing reaction catalyzed ... -
Structure and dynamics of a human myelin protein P2 portal region mutant indicate opening of the β barrel in fatty acid binding proteins
(Peer reviewed; Journal article, 2018-06-25)Background: Myelin is a multilayered proteolipid sheath wrapped around selected axons in the nervous system. Its constituent proteins play major roles in forming of the highly regular membrane structure. P2 is a myelin-specific ... -
Structure and function of an atypical homodimeric actin capping protein from the malaria parasite
(Journal article; Peer reviewed, 2022)Apicomplexan parasites, such as Plasmodium spp., rely on an unusual actomyosin motor, termed glideosome, for motility and host cell invasion. The actin filaments are maintained by a small set of essential regulators, which ... -
Structure and substrate specificity determinants of the taurine biosynthetic enzyme cysteine sulphinic acid decarboxylase
(Journal article; Peer reviewed, 2021)Pyridoxal 5́-phosphate (PLP) is an important cofactor for amino acid decarboxylases with many biological functions, including the synthesis of signalling molecules, such as serotonin, dopamine, histamine, γ-aminobutyric ... -
Structure of the ALS Mutation Target Annexin A11 Reveals a Stabilising N-Terminal Segment
(Journal article; Peer reviewed, 2020)The functions of the annexin family of proteins involve binding to Ca2+, lipid membranes, other proteins, and RNA, and the annexins share a common folded core structure at the C terminus. Annexin A11 (AnxA11) has a long ... -
Structure of the Complete Dimeric Human GDAP1 Core Domain Provides Insights into Ligand Binding and Clustering of Disease Mutations
(Journal article; Peer reviewed, 2021)Charcot-Marie-Tooth disease (CMT) is one of the most common inherited neurological disorders. Despite the common involvement of ganglioside-induced differentiation-associated protein 1 (GDAP1) in CMT, the protein structure ... -
Structure of the mouse acidic amino acid decarboxylase GADL1
(Journal article; Peer reviewed, 2018)Pyridoxal 5′-phosphate (PLP) is a ubiquitous cofactor in various enzyme classes, including PLP-dependent decarboxylases. A recently discovered member of this class is glutamic acid decarboxylase-like protein 1 (GADL1), ... -
Structure of transmembrane prolyl 4-hydroxylase reveals unique organization of EF and dioxygenase domains
(Journal article; Peer reviewed, 2021)Prolyl 4-hydroxylases (P4Hs) catalyze post-translational hydroxylation of peptidyl proline residues. In addition to collagen P4Hs and hypoxia-inducible factor P4Hs, a third P4H—the poorly characterized endoplasmic ... -
