Purification, characterization, and crystallization of monoamine oxidase from Escherichia coli K-12.
The gene for monoamine oxidase (MAO) was cloned from an Escherichia coli genomic library and MAO was overproduced in the periplasmic space, and was found to be a dimer of identical subunits with a molecular weight of 80,000, and showed the highest activity at pH 7.5. Expand
A sulfur- and tyramine-regulated Klebsiella aerogenes operon containing the arylsulfatase (atsA) gene and the atsB gene
The structural gene for arylsulfatase (atsA) of Klebsiella aerogenes was cloned into a pKI212 vector in Escherichia coli andletion analysis suggests that atsB is a potential positive factor for the regulation of arysulfat enzyme. Expand
Lipophilization of lysozyme by short and middle chain fatty acids.
Lipophilization broadened the bactericidal action of lysozyme to Gram-negative bacteria with little loss of enzymatic activity. Expand
Bactericidal action of egg yolk phosvitin against Escherichia coliunder thermal stress.
The results suggest that a significant part of the bactericidal activity of phosvitin against E. coli resides in the synergistic effect of the high metal-chelating ability and the high surface activity under the influence of thermal stress. Expand
Effects of Er:YAG laser irradiation on biofilm-forming bacteria associated with endodontic pathogens in vitro.
The Er:YAG laser was effective against biofilms of 6 of the bacterial species examined, with the exception of those formed by L. casei. Expand
Effects of the tea catechin epigallocatechin gallate on Porphyromonas gingivalis biofilms
The aim of this study was to investigate the effects of tea catechin epigallocatechin gallate (EGCg) on established biofilms and biofilm formation by Porphyromonas gingivalis, a major pathogen ofExpand
Nucleotide sequence of the gene for monoamine oxidase (maoA) from Escherichia coli
It is concluded that the gene encodes for monoamine oxidase ( maoA E ), which was located at 30.9 min on the Escherichia coli chromosome and was located by comparison with amino acid sequences at the cofactor sites in other copper/topa quinone-containing amine oxidases. Expand
Role of amyloid type cross beta-structure in the formation of soluble aggregate and gel in heat-induced ovalbumin.
The results suggest that the amyloidogenic intermolecular beta-structure is involved in the formation of soluble aggregate and gel of heat-induced ovalbumin. Expand
Antibiofilm Effects of Azithromycin and Erythromycin on Porphyromonas gingivalis
It is suggested that AZM is effective against P. gingivalis biofilms at sub-MIC levels and could have future clinical application for oral biofilm infections, such as chronic marginal and periapical periodontitis. Expand
The Inhibitory Effects of Catechins on Biofilm Formation by the Periodontopathogenic Bacterium, Eikenella corrodens
The studies suggest that some species of catechins with the galloyl group affect autoinducer 2-mediated quorum sensing and thereby inhibit biofilm formation by E. corrodens. Expand
