Second, residues in the reactive site of the inhibitor were replaced by the consensus substrate recognition sequence of furin, namely, Arg at P_1, Lys at P_2, Arg at P_4 and Arg at P_6. In addition, the P_7 residue Asp was substituted with Ala to avoid possible electrostatic interference with furin inhibition. Finally, the extra N and C terminal residues beyond the doubly conjugated disulfide loops were further truncated. However, all resultant synthetic peptides were found to be temporary inhibitors of furin and kexin during a prolonged incubation, with the scissile peptide bond between P1 and P'1 cleaved to different extents by the enzymes.

As our base we sat in a circle and did the sequence of floor exercises I developed to stretch and strengthen, and clapped rhythms. The students took turns moving around the outside of the circle while the students sitting clapped sets of (1, 2, 3, 4) and substituted silent claps for each of the numbers. These students, age 5 to 9, though academically challenged could, nonetheless, clap the patterns rhythmically, somatically. This period of time added to the material for the text Adaptive Rhythmic Movement for Children to Seniors.

Second,the sterically demanding substituted magnesium alcoholates can be prepared from dialkylmagnesiums R_2Mg and alcohol.The main disadvantage of this synthesis route lies in the fact that relative expensive dialkyl magnesium compounds,such as Et_2Mg for example,have to be used as starting materials.For this problem,a convenient preparation route of pure dialkylmagnesium from a Grignard reagent.
