Abstract
It is known that fr. V boyioe serum albumin (BSA) contains some enzyme (s) in it as a contaminant. Thus fr. V BSA is cleaved, if it is incubated under certain conditions. In this paper the enzymatic cleavage of fr. V BSA was studied in the presence of tetradecyltrimethylammonium bromide (TTAB). When a molar ratio of TTAB/BSA was 50 or 100, more marked cleavage occurred than when it was 10, and than when that of SDS/BSA (SDS : sodium dodecyl sulfate) was 100. This indicates that the proteolysis occurs more markedly when the unfolding of BSA is more marked.
