title: Analysis of Bacillus megaterium lipolytic system and cloning of LipA, a novel subfamily I.4 bacterial lipase.
abstract: The lipolytic system of Bacillus megaterium 370 was investigated, showing the existence of at least two secreted lipases and a cell-bound esterase. A gene coding for an extracellular lipase was isolated and cloned in Escherichia coli. The cloned enzyme displayed high activity on short to medium chain length (C(4)-C(8)) substrates, and poor activity on C(18) substrates. On the basis of amino acid sequence homology, the cloned lipase was classified into subfamily I.4 of bacterial lipases.
