A study of calf-thymus histone H2B using 13C magnetic resonance.
Calf thymus histone H2B has been studied by means of 13c magnetic resonance. Most sidechain resonances have been assigned. Analysis of 13c peak intensities by a simple computer-aided method proves that 13c magnetic resonance spectroscopy can be used to monitor aggregation phenomena more accurately than 1H magnetic resonance or other physico-chemical methods. Re-examination of 1H spectral simulations shows substantial agreement with 13C results. It is concluded that in 0.1M added NaCL the H2b aggregates include the chain segment from 50 (+/-5) to 108 (+/-5).
