Cold adapted enzymes.
The number of reports on enzymes from cold adapted organisms has increased significantly over the past years, and reveals that adaptive strategies for functioning at low temperature varies amongExpand
Specific radiation damage can be used to solve macromolecular crystal structures.
The use of third generation synchrotron sources has led to renewed concern about the effect of ionizing radiation on crystalline biological samples. In general, the problem is seen as one to beExpand
Crystal Structure of the Mobile Metallo-β-Lactamase AIM-1 from Pseudomonas aeruginosa: Insights into Antibiotic Binding and the Role of Gln157
ABSTRACT Metallo-β-lactamase (MBL) genes confer resistance to virtually all β-lactam antibiotics and are rapidly disseminated by mobile genetic elements in Gram-negative bacteria. MBLs belong toExpand
Crystal structure of alkaline phosphatase from the Antarctic bacterium TAB5.
Alkaline phosphatases (APs) are non-specific phosphohydrolases that are widely used in molecular biology and diagnostics. We describe the structure of the cold active alkaline phosphatase from theExpand
Structural and functional properties of isocitrate dehydrogenase from the psychrophilic bacterium Desulfotalea psychrophila reveal a cold-active enzyme with an unusual high thermal stability.
Isocitrate dehydrogenase (IDH) has been studied extensively due to its central role in the Krebs cycle, catalyzing the oxidative NAD(P)(+)-dependent decarboxylation of isocitrate toExpand
Functional and structural studies of a novel cold-adapted esterase from an Arctic intertidal metagenomic library
A novel cold-adapted lipolytic enzyme gene, est97, was identified from a high Arctic intertidal zone sediment metagenomic library. The deduced amino acid sequence of Est97 showed low similarity withExpand
The structure of bovine lysosomal alpha-mannosidase suggests a novel mechanism for low-pH activation.
Lysosomal alpha-mannosidase (LAM: EC belongs to the sequence-based glycoside hydrolase family 38 (GH38). Two other mammalian GH38 members, Golgi alpha-mannosidase II (GIIAM) and cytosolicExpand
Structure of Phenylalanine Hydroxylase from Colwellia psychrerythraea 34H, a Monomeric Cold Active Enzyme with Local Flexibility around the Active Site and High Overall Stability*
The characteristic of cold-adapted enzymes, high catalytic efficiency at low temperatures, is often associated with low thermostability and high flexibility. In this context, we analyzed theExpand
Structural and computational investigations of VIM-7: insights into the substrate specificity of vim metallo-β-lactamases.
The presence of metallo-β-lactamases (MBLs) in many clinically important human bacterial pathogens limits treatment options, as these enzymes efficiently hydrolyze nearly all β-lactam antibiotics.Expand
The Structure of Bovine Lysosomal α-Mannosidase Suggests a Novel Mechanism for Low-pH Activation
Abstract Lysosomal α-mannosidase (LAM: EC belongs to the sequence-based glycoside hydrolase family 38 (GH38). Two other mammalian GH38 members, Golgi α-mannosidase II (GIIAM) and cytosolicExpand
