Essential role of the C-terminal helical domain in active site formation of selenoprotein MsrA from Clostridium oremlandii. [PDF]

open access: yesPLoS ONE, 2015
We previously determined the crystal structures of 1-Cys type selenoprotein MsrA from Clostridium oremlandii (CoMsrA). The overall structure of CoMsrA is unusual, consisting of two domains, the N-terminal catalytic domain and the C-terminal distinct ...

Catalytic Domain Architecture of Metzincin Metalloproteases [PDF]

open access: yesJournal of Biological Chemistry, 2009
Metalloproteases cleave proteins and peptides, and deregulation of their function leads to pathology. An understanding of their structure and mechanisms of action is necessary to the development of strategies for their regulation. Among metallopeptidases are the metzincins, which are mostly multidomain proteins with approximately 130-260-residue ...

A novel protein kinase-like domain in a selenoprotein, widespread in the tree of life. [PDF]

open access: yes, 2012
Selenoproteins serve important functions in many organisms, usually providing essential oxidoreductase enzymatic activity, often for defense against toxic xenobiotic substances.

The chitinase C gene PsChiC from Pseudomonas sp. and its synergistic effects on larvicidal activity

open access: yesGenetics and Molecular Biology, 2015
Pseudomonas sp. strain TXG6-1, a chitinolytic gram-negative bacterium, was isolated from a vegetable field in Taixing city, Jiangsu Province, China. In this study, a Pseudomonas chitinase C gene (PsChiC) was isolated from the chromosomal DNA of this ...

High-resolution NMR studies of structure and dynamics of human ERp27 indicate extensive interdomain flexibility [PDF]

open access: yes, 2013
ERp27 (endoplasmic reticulum protein 27.7 kDa) is a homologue of PDI (protein disulfide-isomerase) localized to the endoplasmic reticulum. ERp27 is predicted to consist of two thioredoxin-fold domains homologous with the non-catalytic b and b' domains of

CATALYTIC PROPERTIES OF THE EUKARYOTIC EXOSOME [PDF]

open access: yes, 2010
The eukaryotic exosome complex is built around the backbone of a 9‑subunit ring similar to phosporolytic ribonucleases such as RNase PH and polynucleotide phosphorylase (PNPase).

Crystal Structure of Human Nocturnin Catalytic Domain [PDF]

open access: yesScientific Reports, 2018
Abstract Nocturnin (NOCT) helps the circadian clock to adjust metabolism according to day and night activity. NOCT is upregulated in early evening and it has been proposed that NOCT serves as a deadenylase for metabolic enzyme mRNAs. We present a 2.7-Å crystal structure of the catalytic domain of human NOCT.
