SsoII-like DNA-methyltransferase Ecl18kI: interaction between regulatory and methylating functions.

The interaction of DNA-methyltransferase Ecl18kI (M.Ecl18kI) with a fragment of promoter region of restriction-modification system SsoII was studied. It is shown that dissociation constants of M.

Studying the spatial organization of membrane proteins by means of tritium stratigraphy: bacteriorhodopsin in purple membrane.

The topography of bacteriorhodopsin (bR) in situ was earlier studied by using the tritium bombardment approach [Eur. J. Biochem.
