Cloning, expression, purification and preliminary X-ray analysis of a putative metagenome-derived lipase.

ABSTRACT: LipS is a novel thermostable putative lipase that was isolated from a metagenomic library using functional screening methods. The corresponding gene shows high similarity to that encoding a putative but uncharacterized esterase from Symbiobacterium thermophilum IAM14863 (99% nucleotide-sequence similarity). Two different constructs of the recombinant lipase were crystallized. Crystals belonging to space group P4(2)2(1)2 diffracted X-ray radiation to 2.8 Å resolution and crystals belonging to space group P4 diffracted to 2.0 Å resolution. The most probable content of their asymmetric units were two molecules (P4(2)2(1)2) and four or five molecules (P4), respectively.
