Calmodulin is a subunit of lysine sensitive isoenzyme of aspartate kinase from plants

, : Calmodulin is a subunit of lysine sensitive isoenzyme of aspartate kinase from plants. Proceedings of the International Congress of Plant Physiology, New Delhi, India 15-20 February, 1988 Volume 1: 700-704

The lysine sensitive isoenzyme of aspartate kinase was purified 450-fold from spinach leaves. The enzyme with a specific activity of 920 units/mg protein and MW of 300 kDa was resolved into its subunits using 4 M urea. The smaller subunit (17 kDa) showed molecular properties identical to those of calmodulin. The subunit activated other calmodulin-responding enzymes.

Binding of CaMKII (Ca(2+)/calmodulin-dependent protein kinase II) to the NR2B subunit of the NMDAR (N-methyl-D-aspartate-type glutamate receptor) in the PSD (postsynaptic density) is essential for the induction of long-term potentiation.
