    Protein Summary

    The TM0755 gene from Thermotoga maritima codes for protein containing 2 easily distinguished domains.  The N-terminal domain belongs to the lactamase B superfamily (PF00753), while the C-terminal domain belongs to the FMN redox superfamily (PF00258).  The beta-lactamase domain has been reported for many proteins [Ref].  The crystal structure of highly homologous beta-lactamase from Bacillus cereus has been deposited 1BMC.  This type of beta-lactamases require Zn2+ ions for catalysis.  Although no Zn ions are found in the TMO755 structure, the proper spacing of histidine residues at positions 74, 79 and 84 indicates possible metal ion coordination site.  The flavoprotein domain of the TM0755 is a part of proteins that function in various electron transport systems.  The role of this domain in the context of beta-lactamase domain is unclear but genome context suggests a role in oxidative stress protection (high probability of functional association with rubredoxin, rubrerythrin, alkyl hydroperoxide reductase, superoxide reductase).
