One-carbon metabolism in cancer [PDF]
Cells require one-carbon units for nucleotide synthesis, methylation and reductive metabolism, and these pathways support the high proliferative rate of cancer cells.

Iterative focused screening with biological fingerprints identifies selective Asc-1 inhibitors distinct from traditional high throughput screening [PDF]
N-methyl-d-aspartate receptors (NMDARs) mediate glutamatergic signaling that is critical to cognitive processes in the central nervous system, and NMDAR hypofunction is thought to contribute to cognitive impairment observed in both schizophrenia and ...

Controlled rotation mechanism of DNA strand exchange by the Hin serine recombinase. [PDF]
DNA strand exchange by serine recombinases has been proposed to occur by a large-scale rotation of halves of the recombinase tetramer. Here we provide the first direct physical evidence for the subunit rotation mechanism for the Hin serine invertase ...

ABSTRACT Serine resolvases are an interesting group of site-specific recombinases that, in their native contexts, resolve large fused replicons into smaller separated ones. Some resolvases are encoded by replicative transposons and resolve the transposition product, in which the donor and recipient molecules are fused, into separate replicons.

The Bacillus subtilis signaling protein SpoIVB defines a new family of serine peptidases [PDF]
The protein SpoIVB plays a key role in signaling in the sigma (K) checkpoint of Bacillus subtilis. This regulatory mechanism coordinates late gene expression during development in this organism and we have recently shown SpoIVB to be a serine peptidase ...

Making serine integrases work for us [PDF]
DNA site-specific recombinases are enzymes (often associated with mobile DNA elements) that catalyse breaking and rejoining of DNA strands at specific points, thereby bringing about precise genetic rearrangements.

Diversity in the serine recombinases [PDF]
SummaryMost site‐specific recombinases fall into one of two families, based on evolutionary and mechanistic relatedness. These are the tyrosine recombinases orλintegrase family and the serine recombinases or resolvase/invertase family. The tyrosine recombinases are structurally diverse and functionally versatile and include integrases, resolvases ...

Phosphofructokinase 1 Glycosylation Regulates Cell Growth and Metabolism [PDF]
Cancer cells must satisfy the metabolic demands of rapid cell growth within a continually changing microenvironment. We demonstrated that the dynamic posttranslational modification of proteins by O-linked β-N-acetylglucosamine (O-GlcNAcylation) is a key ...

Orchestrating serine resolvases [PDF]
A remarkable feature of the serine resolvases is their regulation: the wild-type enzymes will catalyse intra- but not inter-molecular recombination, can sense the relative orientation of their sites and can exchange strands directionally, despite the fact that there is no net release of chemical bond energy.

PRK1 phosphorylates MARCKS at the PKC sites: serine 152, serine 156 and serine 163
The 80kDa yristolated lanine‐ich ‐inase ubstrate (MARCKS) in a major in vivo substrate of protein kinase C (PKC). Here we report that MARCKS is a major substrate for the lipid‐activated PKC‐related kinase (PRK1) in cell extracts. Furthermore, PRK1 is shown to phosphorylate MARCKS on the same sites as PKC in vitro.
