Mycobacterium tuberculosis (Mtb) uses maltose-1-phosphate to synthesize α-glucans that make up the major component of its outer capsular layer. Maltose kinase (MaK) catalyzes phosphorylation of maltose. The molecular basis for this phosphorylation is currently not understood. Here, we describe the
Sugar metabolism by Streptococcus mutans is associated with tooth decay. The most abundant sugars in the human diet are sucrose and maltose, a derivative of starch. Previously, we reported a binding protein-dependent transport system (msm) in S. mutans that transports sucrose and maltose, but its
A novel maltose-forming α-amylase (PSMA) was recently found in the hyperthermophilic archaeon Pyrococcus sp. ST04. This enzyme shows <13% amino-acid sequence identity to other known α-amylases and displays a unique enzymatic property in that it hydrolyzes both α-1,4-glucosidic and α-1,6-glucosidic
SCO7518 is a protein of unknown function from Streptomyces coelicolor A3(2) that has been classified into the TetR transcriptional regulator family. In this study, a crystal structure of SCO7518 was determined at 2.29Å resolution. The structure is a homodimer of protomers that comprise an N-terminal
Pre-mRNA splicing takes place in a large and highly dynamic complex known as the spliceosome. Here we report the optimization of a maltose-binding protein (MBP) affinity-purification method to isolate functional spliceosomes for electron microscopic analysis. Visualization of the spliceosome
