Lipases, mainly of microbial origin, represent the most widely used class o
f enzymes in biotechnological applications and organic chemistry. Modern me
thods of genetic engineering combined with an increasing knowledge of struc
ture and function will allow further adaptation to industrial needs and exp
loration of novel applications. Production of such tailored lipases require
s their functional overexpression in a suitable host. Hence, this article d
escribes the functional heterologous production of commercially important m
icrobial lipases. Based on the knowledge of different lipases' substrate bi
nding sites, the most suitable lipase for a particular application may be s
elected. (C) 1999 Elsevier Science Ltd. All rights reserved.
