Abstract
Triosephosphate isomerases (TPIs) from Taenia solium (TsTPI) and
Schistosoma mansoni (SmTPI) are potential vaccine and drug
targets against cysticercosis and schistosomiasis, respectively. This is due to
the dependence of parasitic helminths on glycolysis and because those proteins
elicit an immune response, presumably due to their surface localization. Here we
report the crystal structures of TsTPI and SmTPI in complex with
2-phosphoglyceric acid (2-PGA). Both TPIs fold into a dimeric (β-α)8
barrel in which the dimer interface consists of α-helices 2, 3, and 4, and
swapping of loop 3. TPIs from parasitic helminths harbor a region of three amino
acids knows as the SXD/E insert (S155 to E157 and S157 to D159 in TsTPI and
SmTPI, respectively). This insert is located between α5 and β6 and is proposed
to be the main TPI epitope. This region is part of a solvent-exposed
310–helix that folds into a hook-like structure. The crystal
structures of TsTPI and SmTPI predicted conformational epitopes that could be
used for vaccine design. Surprisingly, the epitopes corresponding to the SXD/E
inserts are not the ones with the greatest immunological potential. SmTPI, but
not TsTPI, habors a sole solvent exposed cysteine (SmTPI-S230) and alterations
in this residue decrease catalysis. The latter suggests that thiol-conjugating
agents could be used to target SmTPI. In sum, the crystal structures of SmTPI
and TsTPI are a blueprint for targeted schistosomiasis and cysticercosis drug
and vaccine development. Because of the worldwide prevalence of schistosomiasis and cysticercosis, it is
critical to develop drugs and vaccines against their causative agents. The
glycolytic enzyme triosephosphate isomerase (TPI) is a dual-edged sword against
diseases caused by parasitic helminths. This is because helminths heavily depend
on glycolysis for energy and because the surface localization exhibited by TPIs
that elicits an immune response against those organisms. Here we provide the
crystal structures TPIs from Taenia solium and
Schistosoma mansoni as a first step for vaccine and drug
design. As a proof of concept we found that modifications in the single solvent
exposed cysteine of TPI from S. mansoni
decreases catalysis, making this enzyme a novel target against
schistosomiasis.

Abstract
Triosephosphate isomerase (TIM) is a ubiquitous enzyme, which appeared early in evolution. TIM is responsible for obtaining net ATP from glycolysis and producing an extra pyruvate molecule for each glucose molecule, under aerobic and anaerobic conditions. It is placed in a metabolic crossroad that allows a quick balance of the triose phosphate aldolase produced by glycolysis, and is also linked to lipid metabolism through the alternation of glycerol-3-phosphate and the pentose cycle. TIM is one of the most studied enzymes with more than 199 structures deposited in the PDB. The interest for this enzyme stems from the fact that it is involved in glycolysis, but also in aging, human diseases and metabolism. TIM has been a target in the search for chemical compounds against infectious diseases and is a model to study catalytic features. Until February 2017, 62% of all residues of the protein have been studied by mutagenesis and/or using other approaches. Here, we present a detailed and comprehensive recompilation of the reported effects on TIM catalysis, stability, druggability and human disease produced by each of the amino acids studied, contributing to a better understanding of the properties of this fundamental protein. The information reviewed here shows that the role of the noncatalytic residues depend on their molecular context, the delicate balance between the short and long-range interactions in concerted action determining the properties of the protein. Each protein should be regarded as a unique entity that has evolved to be functional in the organism to which it belongs. Proteins 2017; 85:1190-1211. © 2017 Wiley Periodicals, Inc.

Structural Basis for Redox Regulation of Cytoplasmic and Chloroplastic Triosephosphate Isomerases from Arabidopsis thaliana. FRONTIERS IN PLANT SCIENCE 2016; 7:1817.

Abstract
In plants triosephosphate isomerase (TPI) interconverts glyceraldehyde 3-phosphate (G3P) and dihydroxyacetone phosphate (DHAP) during glycolysis, gluconeogenesis, and the Calvin-Benson cycle. The nuclear genome of land plants encodes two tpi genes, one gene product is located in the cytoplasm and the other is imported into the chloroplast. Herein we report the crystal structures of the TPIs from the vascular plant Arabidopsis thaliana (AtTPIs) and address their enzymatic modulation by redox agents. Cytoplasmic TPI (cTPI) and chloroplast TPI (pdTPI) share more than 60% amino acid identity and assemble as (β-α)8 dimers with high structural homology. cTPI and pdTPI harbor two and one accessible thiol groups per monomer respectively. cTPI and pdTPI present a cysteine at an equivalent structural position (C13 and C15 respectively) and cTPI also contains a specific solvent accessible cysteine at residue 218 (cTPI-C218). Site directed mutagenesis of residues pdTPI-C15, cTPI-C13, and cTPI-C218 to serine substantially decreases enzymatic activity, indicating that the structural integrity of these cysteines is necessary for catalysis. AtTPIs exhibit differential responses to oxidative agents, cTPI is susceptible to oxidative agents such as diamide and H2O2, whereas pdTPI is resistant to inhibition. Incubation of AtTPIs with the sulfhydryl conjugating reagents methylmethane thiosulfonate (MMTS) and glutathione inhibits enzymatic activity. However, the concentration necessary to inhibit pdTPI is at least two orders of magnitude higher than the concentration needed to inhibit cTPI. Western-blot analysis indicates that residues cTPI-C13, cTPI-C218, and pdTPI-C15 conjugate with glutathione. In summary, our data indicate that AtTPIs could be redox regulated by the derivatization of specific AtTPI cysteines (cTPI-C13 and pdTPI-C15 and cTPI-C218). Since AtTPIs have evolved by gene duplication, the higher resistance of pdTPI to redox agents may be an adaptive consequence to the redox environment in the chloroplast.

Abstract
Giardiasis, the most prevalent intestinal parasitosis in humans, is caused by Giardia lamblia. Current drug therapies have adverse effects on the host, and resistant strains against these drugs have been reported, demonstrating an urgent need to design more specific antigiardiasic drugs. ATP production in G. lamblia depends mainly on glycolysis; therefore, all enzymes of this pathway have been proposed as potential drug targets. We previously demonstrated that the glycolytic enzyme triosephosphate isomerase from G. lamblia (GlTIM), could be completely inactivated by low micromolar concentrations of thiol-reactive compounds, whereas, in the same conditions, the activity of human TIM (HuTIM) was almost unaltered. We found that the chemical modification (derivatization) of at least one Cys, of the five Cys residues per monomer in GlTIM, causes this inactivation. In this study, structural and functional studies were performed to describe the molecular mechanism of GlTIM inactivation by thiol-reactive compounds. We found that the Cys222 derivatization is responsible for GlTIM inactivation; this information is relevant because HuTIM has a Cys residue in an equivalent position (Cys217). GlTIM inactivation is associated with a decrease in ligand affinity, which affects the entropic component of ligand binding. In summary, this work describes a mechanism of inactivation that has not been previously reported for TIMs from other parasites and furthermore, we show that the difference in reactivity between the Cys222 in GlTIM and the Cys217 in HuTIM, indicates that the surrounding environment of each Cys residue has unique structural differences that can be exploited to design specific antigiardiasic drugs.
