Research progress on Streptococcus mutans phages in the prevention of dental caries

open access: yes口腔疾病防治, 2021
The Streptococcus mutans (S. mutans) phage, as one of the principal pathogenic bacteria of dental caries, is a main cause of the formation and development of dental caries due to its overproliferation in dental plaque biofilms.

Enzyme systems for fragmentation of the rhamnogalacturonan sites main chains in plant tissue protopectin complex

open access: yesПищевые системы, 2023
Special features of the protopectin complex structure of plant tissue suggest the necessity of performing point destruction of certain glycoside bonds in the structure of rhamnogalacturonan polymer chains for industrial production of pectin. These chains

Structure and mechanism of a phage-encoded SAM lyase revises catalytic function of enzyme family

open access: yeseLife, 2021
The first S-adenosyl methionine (SAM) degrading enzyme (SAMase) was discovered in bacteriophage T3, as a counter-defense against the bacterial restriction-modification system, and annotated as a SAM hydrolase forming 5’-methyl-thioadenosine (MTA) and L ...

Dehydroalanine in Histidine Ammonia Lyase

open access: hybridJournal of Biological Chemistry, 1969
Abstract Preparations of highly purified Pseudomonas histidine ammonia lyase were inactivated by reduction with sodium borotritide. Alanine was the only labeled material in acid hydrolysates of the dialyzed product. Its presence indicates the presence of dehydroalanine (2-aminoacrylic acid) in the enzyme.

Gellan lyases-novel polysaccharide lyases [PDF]

open access: yesMicrobiology, 1994
A number of bacterial strains capable of degrading the bacterial exopolysaccharide gellan have been isolated by standard enrichment procedures. They include several pink-pigmented Gram-negative rod-shaped bacteria. A red-pigmented Gram-positive bacillus earlier found to degrade the exopolysaccharide xanthan from Xanthomonas campestris also showed ...

Pectinolytic lyases: a comprehensive review of sources, category, property, structure, and catalytic mechanism of pectate lyases and pectin lyases [PDF]

open access: yesBioresources and Bioprocessing, 2021
AbstractPectate lyases and pectin lyases have essential roles in various biotechnological applications, such as textile industry, paper making, pectic wastewater pretreatment, juice clarification and oil extraction. They can effectively cleave the α-1,4-glycosidic bond of pectin molecules back bone by β-elimination reaction to produce pectin ...

Adenylosuccinate lyase deficiency [PDF]

open access: yesJournal of Inherited Metabolic Disease, 2014
AbstractAdenylosuccinate lyase ADSL) deficiency is a defect of purine metabolism affecting purinosome assembly and reducing metabolite fluxes through purine de novo synthesis and purine nucleotide recycling pathways. Biochemically this defect manifests by the presence in the biologic fluids of two dephosphorylated substrates of ADSL enzyme ...

Clinical and molecular characterization of patients with adenylosuccinate lyase deficiency

open access: yesOrphanet Journal of Rare Diseases, 2021
Background Adenylosuccinate lyase deficiency (ADSLD) is an ultrarare neurometabolic recessive disorder caused by loss-of-function mutations in the ADSL gene. The disease is characterized by wide clinical variability.
