title: Plausible mechanism of inactivation of plasma alpha 1-proteinase inhibitor by acrolein.
abstract: Evidence is presented to show that inactivation of alpha 1-proteinase inhibitor caused by acrolein depends upon the modification of lysine and histidine residues. Approximately 90% activity was lost when twenty three lysine and eight histidine residues were modified.
