gfsA encodes a novel galactofuranosyltransferase involved in biosynthesis of galactofuranose antigen of O‐glycan in Aspergillus nidulans and Aspergillus fumigatus
The cells walls of filamentous fungi in the genus Aspergillus have galactofuranose (Galf)‐containing polysaccharides and glycoconjugates, including O‐glycans, N‐glycans, fungal‐type galactomannan and… Expand

Chemical Mechanism of UDP-Galactopyranose Mutase from Trypanosoma cruzi: A Potential Drug Target against Chagas' Disease
UDP-galactopyranose mutase (UGM) is a flavoenzyme that catalyzes the conversion of UDP-galactopyranose to UDP-galactofuranose, the precursor of galactofuranose (Galf). Galf is found in several… Expand

Targeting UDP-Galactopyranose Mutases from Eukaryotic Human Pathogens
UDP-Galactopyranose mutase (UGM) is a unique flavin-dependent enzyme that catalyzes the conversion of UDP-galactopyranose (UDP-Galp) to UDP-galactofuranose (UDP-Galf). The product of this reaction is… Expand

Cationic glycopolymers for the delivery of pDNA to human dermal fibroblasts and rat mesenchymal stem cells.
Progenitor and pluripotent cell types offer promise as regenerative therapies but transfecting these sensitive cells has proven difficult. Herein, a series of linear trehalose-oligoethyleneamine… Expand

Substrate‐dependent dynamics of UDP‐galactopyranose mutase: Implications for drug design
Trypanosoma cruzi is the causative agent of Chagas disease, a neglected tropical disease that represents one of the major health challenges of the Latin American countries. Successful efforts were… Expand

Correlation of amine number and pDNA binding mechanism for trehalose-based polycations.
Glycopolymers with repeat units comprised of the disaccharide trehalose and an oligoamine of increasing amine have been previously synthesized by our group and shown to efficiently deliver pDNA… Expand

UDP-galactopyranose mutases from Leishmania species that cause visceral and cutaneous leishmaniasis.
Leishmaniasis is a vector-borne, neglected tropical disease caused by parasites from the genus Leishmania. Galactofuranose (Galf) is found on the cell surface of Leishmania parasites and is important… Expand

Contributions of Unique Active Site Residues of Eukaryotic UDP-Galactopyranose Mutases to Substrate Recognition and Active Site Dynamics
UDP-galactopyranose mutase (UGM) catalyzes the interconversion between UDP-galactopyranose and UDP-galactofuranose. Absent in humans, galactofuranose is found in bacterial and fungal cell walls and… Expand

A fluorescence polarization binding assay to identify inhibitors of flavin-dependent monooxygenases.
N-Hydroxylating monooxygenases (NMOs) are essential for pathogenesis in fungi and bacteria. NMOs catalyze the hydroxylation of sine and ornithine in the biosynthesis of hydroxamate-containing… Expand

Inhibition of the Flavin-Dependent Monooxygenase Siderophore A (SidA) Blocks Siderophore Biosynthesis and Aspergillus fumigatus Growth.
Aspergillus fumigatus is an opportunistic fungal pathogen and the most common causative agent of fatal invasive mycoses. The flavin-dependent monooxygenase siderophore A (SidA) catalyzes the oxygen… Expand
