The globin in cytosol receives the heme in mitochondria and folds to the hemoglobin within erythrocyte. Two mechanisms have been proposed that the heme was transfered post-translationally or cotranslationally to the globin. In this research, how the globin in cytosol receives post-translationally the heme from membranes was studied according to pH and phospholipid composition. Globins dissolved in various pH buffer solutions $(PH;3~7)$ were rapidly added into the bulk of egg phosphatidylcholine $100\%;or;60\%$ liposomes containing hemin in pH 7 buffer solution. Hemin was very highly transferred to globin at pH 4 and 6. Also, hemin was more efficiently transfered to globin in egg phosphatidylcholine $100\%$ than in $60\%$ liposomes.
