Propionate in Heme Biosynthesis in Soybean Nodules 1
AUTOR(ES)
Jackson, Earl K.
RESUMO
When soybean nodules are incubated with propionate-2-14C the heme moiety of leghemoglobin becomes labeled. The incorporation of propionate-2-14C into heme is linear with time and it appears that propionate is utilized without a lag period. The rate of incorporation of propionate-2-14C into heme is more rapid than the rate of incorporation of succinate-2-14C and citrate-1,5-14C, however, these rates of incorporation may be influenced by different sizes of endogenous pools of organic acids.
