Journal ArticleDOI
Pyruvate kinase: current status of regulatory and functional properties.
TL;DR: The results of a current and extensive review that determines the sites of conservation and/or difference in PK sequences, and the differences in the functional and regulatory properties of the enzymes are described.
Journal ArticleDOI
Nonylphenol, an integrated vision of a pollutant. Scientific review
Rafael Vazquez-Duhalt,Facundo J. Márquez-Rocha,Elizabeth Ponce,Alexei Fedorovish Licea Navarro,María Teresa Viana +4 more
TL;DR: In this paper, the authors performed a critical review on the origin, environmental fate, microbial transformation, ecosystems impact and endocrine disruption capacity of nonylphenol, which is a metabolic intermediate from the microbial transformation of detergents used worldwide.
Journal ArticleDOI
Cloning of the two pyruvate kinase isoenzyme structural genes from Escherichia coli: the relative roles of these enzymes in pyruvate biosynthesis.
TL;DR: The cloning of the pykA and pykF genes from Escherichia coli, which code for the two pyruvate kinase isoenzymes, were reported, which were insertionally inactivated with antibiotic resistance markers and utilized to interrupt one or both pyk genes in the E. coli chromosome.
Journal ArticleDOI
Prevalence and characterization of Salmonella enterica serovar Weltevreden from imported seafood.
Elizabeth Ponce,Elizabeth Ponce,Ashraf A. Khan,Chorng-Ming Cheng,Christine Summage-West,Carl E. Cerniglia +5 more
TL;DR: The findings show genetic diversity and temporal persistence of S. enterica serovar Weltevreden in recently monitored seafood imports and a low frequency of antibiotic resistance.
Journal ArticleDOI
Nonylphenol algal bioaccumulation and its effect through the trophic chain.
Gabriel Correa-Reyes,María Teresa Viana,Facundo J. Márquez-Rocha,Alexei Licea,Elizabeth Ponce,Rafael Vazquez-Duhalt +5 more
TL;DR: Results showed that organisms placed in the first level of trophic chain are able to significantly bioconcentrate the pollutant and endocrine disruptor NP, which affects the growth of crustacean and the environmental presence of NP should be considered as a risk for the organisms living in an ecosystem.
