This entry represents the N-terminal domain of BREX system Lon protease-like protein BrxL from Bacillus cereus and similar proteins. BrxL is part of a type 1 BREX system, which contains a C-terminal Lon-like protease domain (Pfam:PF05362). BREX systems (bacteriophage exclusion) provide immunity against bacteriophage, a system that allows phage adsorption but prevents phage DNA replication, without degradation of the phage DNA [1].

The Lon serine proteases must hydrolyse ATP to degrade protein substrates. In Escherichia coli, these proteases are involved in turnover of intracellular proteins, including abnormal proteins following heat-shock. The active site for protease activity resides in a C-terminal domain. The Lon proteases are classified as family S16 in Merops.	Domain

This entry represents the ATPase domain found in BREX system Lon protease-like protein BrxL from Bacillus cereus and similar proteins. BrxL is part of a type 1 BREX system which contains a C-terminal Lon-like protease domain (Pfam:PF05362. BREX systems (bacteriophage exclusion) provide immunity against bacteriophage, a system that allows phage adsorption but prevents phage DNA replication, without degradation of the phage DNA [1]. Methylation of bacterial DNA by PglX probably guides self/non-self discrimination. This entry also includes a few uncharacterised viral sequences.	Domain
