Phosphorylation of Serine-15 of Maize Leaf Sucrose Synthase (Occurrence in Vivo and Possible Regulatory Significance)
Experiments were conducted to determine whether sucrose synthase (SuSy) was phosphorylated in the elongation zone of maize (Zea mays L.) leaves. The approximately 90-kD subunit of SuSy was… Expand

Nonlinear optical properties of tetra-tert.-butyl-oligo (rylene) s
Abstract Third harmonic generation (THG) measurements are described for a series of tetra-tert.-butyl-oligo(rylene)s. The values of the nonlinear susceptibility χ(3)(−3ω;ω,ω,ω) of the smaller rylene… Expand
