| Abstract: | A truncated apolipoprotein (apo) A-I with a molecular weight (M r) of 26 kDa was first isolated from the plasma high density lipoproteins of an atypical Japanese eel (Anguilla japonica). Interestingly, this eel contained a very small amount of intact apoA-I (M r28 kDa) in the plasma, although serine protease inhibitors were present throughout the plasma preparation. The N-terminal sequence of 20 amino acids in truncated apoA-I was completely identical with that of intact apoA-I. Another apolipoprotein with M r28 kDa, whose N-terminal amino acid sequence differed from apoA-I, was also found in high density lipoprotein and low density lipoprotein. The apolipoprotein profiles of Japanese eel plasma appear to be complicated. |
