Imino-Acids in Santalum Leaves [PDF]

Nature, 1955
ATTENTION has been directed by Giri, Gopalkrishnan, Radhakrishnan and Vaidyanathan1 to the high content of free hydroxyproline in the leaves of Santalum album L., and of free proline in the leaves of various species of Citrus. Their observations are of interest, as these imino-acids have previously been reported only as minor constituents of the ...

Interplay of 'induced fit' and preorganization in the ligand induced folding of the aptamer domain of the guanine binding riboswitch [PDF]

, 2006
Riboswitches are highly structured elements in the 50-untranslated regions (50-UTRs) of messenger RNA that control gene expression by specifically binding to small metabolite molecules. They consist of an aptamer domain responsible for ligand binding and
