An enzyme catalyzing the formation of delta-aminolevulinic acid by transamination of gamma,delta-dioxovaleric acid with l-alpha-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 delta-aminolevulinic acid metabolism in plants is not clearly understood.
在小球藻提取物中检测到一种酶,该酶可通过γ,δ-二氧戊酸与L-α-丙氨酸、L-谷氨酸或L-苯丙氨酸的转氨作用催化δ-氨基乙酰丙酸的形成。在需要光照来产生叶绿素的小球藻突变体中,这种酶的活性似乎与叶绿素含量的变化并不平行。目前尚不清楚这种酶在植物δ-氨基乙酰丙酸代谢中的作用。
