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

Structure- and context-based analysis of the GxGYxYP family reveals a new putative class of glycoside hydrolase. [PDF]
BackgroundGut microbiome metagenomics has revealed many protein families and domains found largely or exclusively in that environment. Proteins containing the GxGYxYP domain are over-represented in the gut microbiota, and are found in Polysaccharide ...

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

Structure, function and inhibition of poly(ADP-ribose)polymerase, member 14 (PARP14) [PDF]
Poly(ADP-ribose)polymerase, member 14 (PARP14, alternatively named ARTD8, BAL2, and COAST6) is an intracellular mono(ADP-ribosyl) transferase. PARP14 transfers a negatively charged ADP-ribose unit from a donor NAD+ molecule onto a target protein, post ...

Two Catalytic Domains Are Required for Protein Deacetylation [PDF]
Histone deacetylase (HDAC)-6 was recently identified as a dual substrate, possibly multisubstrate, deacetylase that can act both on acetylated histone tails and on alpha-tubulin acetylated on Lys40. HDAC-6 is unique among deacetylases in having two hdac domains, and we have used this enzyme as a useful model to dissect the structural requirements for ...

Phosphorylated claspin interacts with a phosphate-binding site in the kinase domain of Chk1 during ATR-mediated activation [PDF]
Claspin is essential for the ATR-dependent activation of Chk1 in Xenopus egg extracts containing incompletely replicated or UV-damaged DNA. The activated form of Claspin contains two repeated phosphopeptide motifs that mediate its binding to Chk1.

Structural rearrangement of CaMKIIα catalytic domains encodes activation [PDF]
At its fundamental level, human memory is thought to occur at individual synaptic contact sites and manifest as persistent changes in synaptic efficacy. In digital electronics, the fundamental structure for implementing memory is the flip-flop switch, a circuit that can be triggered to flip between two stable states.

Allosteric Regulation Alters Carrier Domain Translocation in Pyruvate Carboxylase [PDF]
Pyruvate carboxylase (PC) catalyzes the ATP-dependent carboxylation of pyruvate to oxaloacetate. The reaction occurs in two separate catalytic domains, coupled by the long-range translocation of a biotinylated carrier domain (BCCP). Here, we use a series
