Effects of penicillin and glycine on cell wall glycopeptides of the two varieties of Vibrio fetus.

Journal of Bacteriology

Abstract

Actively growing strains of Vibrio fetus venerealis and V. fetus intestinalis, none of which produced penicillinase, were treated with inhibitory levels of penicillin or glycine, primarily to gain insight into the differential sensitivities of the two varieties to both of these compounds. Treatments induced the accumulation of uridine nucleotide glycopeptide precursors which contained amino sugars and amino acids in various molar ratios. Penicillin-induced nucleotides all contained muramic acid and sometimes glucosamine; they generally contained alanine, glutamic acid, diaminopimelic acid, and glycine. Approximately equimolar ratios of these components were observed in some compounds, but ratios varied considerably in others. Glycine-induced nucleotides contained muramic acid and, in some instances, glucosamine. Amino acids were detected only infrequently and usually in low molar ratios. The data suggest that penicillinase production, differences in the chemical composition of glycopeptide, and variations in modes of action of penicillin and glycine cannot individually account for the differential sensitivities of venereal and intestinal strains of V. fetus to these substances.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Regulation of Vocal-Motor Plasticity

Dopaminergic projections to the basal ganglia and nucleus accumbens shape the learning and plasticity of motivated behaviors across species including the regulation of vocal-motor plasticity and performance in songbirds. Discover the latest research on the regulation of vocal-motor plasticity here.

Myocardial Stunning

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.
