Lipolytic enzymes have attracted attention from a global market because they show enormous biotechnological potential for applications such as detergent production, leather processing, cosmetics production, and use in perfumes and biodiesel. Due to the intense demand for biocatalysts, a metagenomic approach provides methods of identifying new enzymes. In(More)
The enzyme glucose-6-phosphate dehydrogenase (G6PDH) catalyzes the first step of the oxidative branch of the pentose phosphate pathway, which provides cells with NADPH, an essential cofactor for many biosynthetic pathways and antioxidizing enzymes. In Trypanosoma cruzi, the G6PDH has being pursued as a relevant target for the development of new drugs(More)
Phosphoglycerate mutases (PGAMs) participate in both the glycolytic and the gluconeogenic pathways in reversible isomerization of 3-phosphoglycerate and 2-phosphoglycerate. PGAMs are members of two distinct protein families: enzymes that are dependent on or independent of the 2,3-bisphosphoglycerate cofactor. We determined the X-ray structure of the(More)
Esterases catalyze the cleavage and formation of ester bonds and are members of the diverse family of α/β hydrolase fold. They are useful in industries from different sectors, such as food, detergent, fine chemicals, and biofuel production. In a previous work, 30 positive clones for lipolytic activity were identified from a metagenomic library of a(More)
The enzyme glucose-6-phosphate dehydrogenase from Trypanosoma cruzi (TcG6PDH) catalyses the first step of the pentose phosphate pathway (PPP) and is considered a promising target for the discovery of a new drug against Chagas diseases. In the present work, we describe the crystal structure of TcG6PDH obtained in a ternary complex with the substrate(More)
