Insights from mammals indicate that two neural circuits are of crucial importance in this context: the social behavior network and the mesolimbic reward system. Here we review evidence from neurochemical, tract-tracing, developmental, and functional lesion/stimulation studies that delineates homology relationships for most of the nodes of these two circuits across the five major vertebrate lineages: mammals, birds. Vertebrates LinkOut - more resources. The polymer was bound to membrane fractions from where it was slowly released during preparation for analysis. Only 12 of the 237 fungi and myxomycetes showed PMLA -hydrolase activity; and two of these were producers of PMLA. Accepted, Available online 9 February 2008. Various fungi and myxomycetes have been tested for their synthesis and hydrolytic degradation of -poly(L-malate) (PMLA a highly anionic polyester of L-malate. The PMLA content of the culture medium, and also of some cell extracts, has been assayed by L-malate dehydrogenase (EC.
