Abstract: | Summary The cellular slime mould Polysphondylium violaceum contains two vegetative stage specific acidic (casein) kinases. These two enzymes have been partially purified and their properties investigated. Both utilise casein as their preferred substrate but they can be distinguished in a number of ways, including their responses to spermine, heparin and salt. In addition, they have different affinities for their substrates and different pH activity profiles. It is suggested that they may play a role in a vegetative specific function such as cell division. |
