Peptidase activity of beta-lactamases.

The Biochemical journal, 1999
Although beta-lactamases have generally been considered as being devoid of peptidase activity, a low but significant hydrolysis of various N-acylated dipeptides was observed with representatives of each class of beta-lactamases. The kcat/Km values were below 0.1 M(-1).

Serious Bacterial Infections in Hospitalized Neonates in Eastern Ethiopia: Investigating the Emerging Pathogen Pantoea dispersa Compared With Klebsiella pneumoniae

Tropical Medicine &International Health, EarlyView.
ABSTRACT Background Serious bacterial infections (SBIs) are major contributors to neonatal morbidity and mortality in low‐income countries. We describe the aetiology and risk factors for neonatal bacteraemia and in‐hospital mortality in eastern Ethiopia, focusing on Pantoea dispersa, a rarely studied pathogen, and Klebsiella pneumoniae.

Functional investigation of the RHD gene promoter: Molecular changes are rarely responsible for variant D phenotype in Thai donors

Transfusion, EarlyView.
Abstract Background While modern technology is increasingly available to identify efficiently the molecular alterations responsible for variant phenotype, a subset of samples still escapes those analyses. In addition to the promoter region, two intronic regions containing GATA1 binding sites within the RHD gene locus were recently shown to modulate the
