ABSTRACT Post‐translational modifications (PTMs) to tubulin subunits in microtubule filaments are thought to comprise a component of the tubulin code that specifies microtubule functions in cell physiology and animal development. Acetylation of Lysine‐40 (K40) on α‐tubulin (αTub‐K40ac) and glutamylation of both α‐ and β‐tubulin are two tubulin PTMs of ...

Predicting Knot and Catenane Type of Products of Site-specific Recombination on Twist Knot Substrates [PDF]
Site-specific recombination on supercoiled circular DNA molecules can yield a variety of knots and catenanes. Twist knots are some of the most common conformations of these products and they can act as substrates for further rounds of site-specific ...

Abstract Background Sporadic venous malformation (VM) is associated with the hyperactivating p.L914F mutation in TIE2, a receptor tyrosine kinase essential for vascular development. This mutation is not found in hereditary VM, suggesting incompatibility with life when expressed during early vascular development.

Attachment Site Selection and Identity in Bxb1 Serine Integrase-Mediated Site-Specific Recombination [PDF]
Phage-encoded serine integrases mediate directionally regulated site-specific recombination between short attP and attB DNA sites without host factor requirements.

Mutational Analysis of the Archaeal Tyrosine Recombinase SSV1 Integrase Suggests a Mechanism of DNA Cleavage in trans [PDF]
The only tyrosine recombinase so far studied in archaea, the SSV1 integrase, harbors several changes in the canonical residues forming the catalytic pocket of this family of recombinases. This raised the possibility of a different mechanism for archaeal tyrosine recombinase.

Two different evolutionary lines of filamentous phages in Ralstonia solanacearum: their effects on bacterial virulence [PDF]
The integration and excision of various filamentous phage genomes into and out of their host chromosomes occurs by site-specific recombination. The mechanisms proposed for these events include reactions mediated by phage-encoded recombinases and host ...

The evolution of tyrosine-recombinase elements in [PDF]
Transposable elements can be categorised into DNA and RNA elements based on their mechanism of transposition. Tyrosine recombinase elements (YREs) are relatively rare and poorly understood, despite sharing characteristics with both DNA and RNA elements.

Unveiling Hidden Catalytic Contributions of the Conserved His/Trp-III in Tyrosine Recombinases: Assembly of a Novel Active Site in Flp Recombinase Harboring Alanine at this Position [PDF]
The catalytic pentad of tyrosine recombinases, that assists the tyrosine nucleophile, includes a conserved histidine/tryptophan (His/Trp-III). Flp and Cre harbor tryptophan at this position; most of their kin recombinases display histidine. Contrary to the conservation rule, Flp(W330F) is a much stronger recombinase than Flp(W330H).

Background and Purpose Cyclic guanosine monophosphate (cGMP) is a ubiquitous second messenger involved in human (patho‐)physiology. Phosphodiesterase 5 (PDE5) is a major cGMP hydrolyzing enzyme in many cell types including vascular smooth muscle cells (VSMCs). Several highly selective PDE5 inhibitors are in clinical use. However, there are currently no

Conservation of structure and function among tyrosine recombinases: homology-based modeling of the lambda integrase core-binding domain [PDF]
Tyrosine recombinases participate in diverse biological processes by catalyzing recombination between specific DNA sites. Although a conserved protein fold has been described for the catalytic (CAT) domains of five recombinases, structural relationships between their core-binding (CB) domains remain unclear.
