An enzyme catalyzing the formation of -aminolevulinic acid by transamination of , -dioxovaleric acid with L- -alanine, L-glutamic acid, or L-phenylalanine has been detected in extracts of Chlorella vulgaris. The activity of this enzyme does not appear to parallel changes in chlorophyll content in a Chlorella mutant which requires light for chlorophyll production. The role of this enzyme in -aminolevulinic acid metabolism in plants is not clearly understood.
