LacED, also known as The Lactamase Engineering Database, is a database that identifies and corrects inconsistencies in already existing databases, namely Beta-lactamases. It integrates such information as mutations, sequence alignments, and structures in order to accomplish the task.^[1] As of the publication of the primary literature, LacED provides 2399 sequences entries and 37 structure entries.^[1] Example of this database in action is shown when 89 proteins from the microbial organisms and 35 proteins from cloning or expression vectors had new mutation profiles.^[1] Additionally, 55 proteins had inconsistent annotations in their TEM assignments or mutation profiles.^[1]
