Phospholipids as dynamic participants in biological processes

Phospholipids as dynamic participants in biological processes.

Phospholipids are described as active biological molecules. Three distinctly different roles are examined. The first centers on protein-lipid interactions and the lipid requirement expressed by certain enzymes. This category is illustrated by two soluble proteins of the blood coagulation scheme, Factor IXa and Factor Xa, and by an integral membrane protein, the (Ca2+ + Mg2+)-ATPase of human ery...

tRNAs as regulators of biological processes

Transfer RNAs (tRNA) are best known for their role as adaptors during translation of the genetic code. Beyond their canonical role during protein biosynthesis, tRNAs also perform additional functions in both prokaryotes and eukaryotes for example in regulating gene expression. Aminoacylated tRNAs have also been implicated as substrates for non-ribosomal peptide bond formation, post-translationa...

Photoactivated biological processes as quantum measurements.

We outline a framework for describing photoactivated biological reactions as generalized quantum measurements of external fields, for which the biological system takes on the role of a quantum meter. By using general arguments regarding the Hamiltonian that describes the measurement interaction, we identify the cases where it is essential for a complex chemical or biological system to exhibit n...

Oxidized Phospholipids: Introduction and Biological Significance

Correction: Tracing dynamic biological processes during phase transition

Correction After the publication of our article [1], we found that a few errors were introduced during the production process. The mathematical definition of expanded temporal block given in Definition 3 (Expanded temporal block) should have been “the corresponding expanded temporal block Bi = {Gi , T∗ i |Gi ⊆ I, Gi ⊇ Gi, T∗ i = Ti} satisfies: ∀x ∈ Gi , ∃y ∈ Gi, s.t. Cx,y ≥ p” rather than “the ...
