It was shown that lanthanide ions with a smaller ionic radius bind sequentially to Cd2+-saturated parvalbumin, whereas those with a larger ionic radius bind with similar affinity to both the CD site and the EF site. The smallest ion, Lu3+, does in fact not compete significantly with Cd2+ for the CD site in carp parvalbumin, but appears to bind only to the EF site. This preference of the smaller lanthanide ions for the EF site was used to assign the n.m.r. signals for protein-bound 113Cd. By using Cd n.m.r. and Tb3+ fluorescence it was also shown for alpha-lineage parvalbumin from pike that these proteins possess a third site that can bind lanthanide ions. This site is, however, much weaker than in the beta-lineage parvalbumins. It was used to assign the 113Cd resonances from protein-bound Cd2+ ions in the spectrum of pike pI5.0 parvalbumin.

Myotropic activities in guinea pig ileum (ED50 = 4.0 +/- 1.5 10(-8) M) and guinea pig trachea (ED50 = 8.6 +/- 3.5 10(-8) M) are discussed in comparison with the corresponding activities of Substance P.

The framework presents a physical reference model and information model. The information model consists of an Energy Management Domain as a set of Energy Objects. Each Energy Object can be attributed with identity, classification, and context. Energy Objects can be monitored and controlled with respect to power, Power State, energy, demand, Power Attributes, and battery. Additionally, the framework models relationships and capabilities between Energy Objects.

This composition is suggested by the molecular weight of about 180 kd determined for the new particle by small angle neutron scattering. The histone fragments differ by about 2-3 kd each from the initial histones H2A, H2B, H3 and H4 and they correspond to the cleavage of the N-terminal part of the sequence (20-30 residues). A preliminary investigation by thermal denaturation, circular dichroism and small angle neutron scattering (measurement of a radius of gyration by the H2O-D2O contrast variation technique) indicates that the spatial organization of the new chromatin particle closely resembles that of the initial core particle.
