Metallo-β-lactamases: a major threat to human health
Antibiotic resistance is one of the most significant challenges facing global healthcare. Since the 1940s, antibiotics have been used to fight infections, initially with penicillin and… Expand

Catalytic mechanisms of metallohydrolases containing two metal ions.
At least one-third of enzymes contain metal ions as cofactors necessary for a diverse range of catalytic activities. In the case of polymetallic enzymes (i.e., two or more metal ions involved in… Expand

Identification and characterization of an unusual metallo-β-lactamase from Serratia proteamaculans
Metallo-β-lactamases (MBLs) are a family of metalloenzymes that are capable of hydrolyzing β-lactam antibiotics and are an important means by which bacterial pathogens use to inactivate antibiotics.… Expand

Unusual metallo-β-lactamases may constitute a new subgroup in this family of enzymes
Metallo-β-lactamases (MBLs) are a family of Zn2+-dependent enzymes that have contributed strongly to the emergence and spread of antibiotic resistance. Novel members as well as variants of… Expand

Copper Ions and Coordination Complexes as Novel Carbapenem Adjuvants
ABSTRACT Carbapenem-resistant Enterobacteriaceae are urgent threats to global human health. These organisms produce β-lactamases with carbapenemase activity, such as the metallo-β-lactamase NDM-1,… Expand

β-Lactam antibiotic-degrading enzymes from non-pathogenic marine organisms: a potential threat to human health
AbstractMetallo-β-lactamases (MBLs) are a family of Zn(II)-dependent enzymes that inactivate most of the commonly used β-lactam antibiotics. They have emerged as a major threat to global healthcare.… Expand

Promiscuous metallo-β-lactamases: MIM-1 and MIM-2 may play an essential role in quorum sensing networks.
MIM-1 and MIM-2 are two recently identified metallo-β-lactamases (MBLs) from Novosphingobium pentaromativorans and Simiduia agarivorans, respectively. Since these organisms are non-pathogenic we… Expand

Intrinsic disorder and metal binding in UreG proteins from Archae hyperthermophiles: GTPase enzymes involved in the activation of Ni(II) dependent urease
Urease is a Ni(II) enzyme present in every domain of life, in charge for nitrogen recycling through urea hydrolysis. Its activity requires the presence of two Ni(II) ions in the active site. These… Expand

Structure and mechanism of potent bifunctional β-lactam- and homoserine lactone-degrading enzymes from marine microorganisms
Genes that confer antibiotic resistance can rapidly be disseminated from one microorganism to another by mobile genetic elements, thus transferring resistance to previously susceptible bacterial… Expand

Identification and preliminary characterization of novel B3-type metallo-β-lactamases
Antibiotic resistance has emerged as a major global threat to human health. Among the strategies employed by pathogens to acquire resistance the use of metallo-β-lactamases (MBLs), a family of… Expand
