Identification of a novel alkaliphilic esterase active at low temperatures by screening a metagenomic library from antarctic desert soil.
A novel esterase was identified through functional screening of a metagenomic library in Escherichia coli obtained from Antarctic desert soil. The 297-amino-acid sequence had only low (<29%) similarity to a putative esterase from Burkholderia xenovorans. The enzyme was active over a temperature range of 7 to 54 degrees C and at alkaline pH levels and is a potential candidate for industrial application.
