Under normal conditions, small molecules, such as sugars and amino acids, with sizes less than 1 kDa (kilodalton), can easily pass through the plasmodesmata. Larger molecules like RNA and proteins can only pass through when the channel size is increased. This can happen due to external influenc...
Whereas it is widely accepted that the transit peptide of the precursor for the light-harvesting chlorophyll a/b protein (preLHCP) is responsible for targeting this polypeptide to chloroplasts, the signals which govern its intraorganellar targeting appears to be transit peptide-mediated for plastocyanin...
Cloning and expression of a cDNA encoding the beta-subunit (30-kDa subunit) of bovine brain platelet-activating factor acetylhydrolase. Bovine brain platelet-activating factor (PAF) acetylhydrolase isoform Ib is a heterotrimeric enzyme. Its gamma-subunit (which, formerly, we called the 29-k... ...

Bovine β-casein comprises 209 amino acids and is considered the most hydrophobic of the caseins. The hydrophobicity seems to play an important role in the attachment of β-casein within the casein micelle. This protein has a flexible and open conformation, molecular mass of 23.6 kDa (primary ...

In addition to the major 340-kDa class of fibrinogen molecules, normal human plasma has been shown to contain a 420-kDa subclass, termed Fib420, in which the two a-chains are replaced by two extended a-chains (OCE) (Fu and Grieninger, Proc Natl Acad Sci USA 1994; 91:2625). The ...
In any biological system with memory, the state of the system depends on its history. Epigenetic memory maintains gene expression states through cell generations without a change in DNA sequence and in the absence of initiating signals. It is immensely powerful in biological systems — it adds lon...
