N-Terminal Sequence and Main Characteristics of Atlantic Salmon (Salmo salar) Albumin.
Atlantic salmon (Salmo salar) serum albumin was purified from plasma and its N-terminal sequence determined. Atlantic salmon albumin is the predominant plasma protein, negatively charged, at pH 8.6. Albumin was purified to >95% purity which yielded a single band on SDS-PAGE and agarose gel electrophoresis. The molecular weight of the purified albumin was approximately 6,5 kDa. The N-terminal sequence of Atlantic chinook salmon albumin was consistent with that predicted from its previously determined cDNA sequence and was identical to that of salmon (Oncorhynchus tshawytscha) albumin through the first 15 residues. However, the fact that the actual N-terminus was different from that predicted from cDNA sequence indicates that Atlantic salmon albumin, like chinook salmon albumin, lacks a propeptide.
