✦ Synopsis

Removal of a methyl group of the allosamizoline moiety of allosamidin decreases the inhibitory effect on family 18 chitinases from three different species (a bacterium, Serratia marcescens, a crustacean, Artemia salina, and an insect cell line, Chironomus tentans). Loss of a second methyl group weakens enzyme inhibition further. This is in agreement with the highly conserved catalytic centre of these enzymes.

The effect of Ca 2ϩ -binding protein regucalcin on protein kinase activity in the nuclei of normal and regenerating rat livers was investigated. Protein kinase activity in the nuclei isolated from normal rat liver was significantly increased by addition of Ca 2ϩ (500 µM) and calmodulin (10 µg/ml) in
