title: The effect of various nucleotides on the helical nature of a ribosomal protein(s) from Escherichia coli.
abstract: In the presence of GTP or GDP, there is a decrease in the circular dichroic absorption of ribosomal proteins L(7) and L(12) at 221-222 nm, suggesting that these nucleotides influence the helical content of these proteins.
