rheum/dental caries

This study aimed to evaluate in vitro effects of Rheum undulatum L. root on the development of dental caries, especially its effects on viability, dental plaque formation, and glycolytic acid production of Streptococcus mutans and Streptococcus sobrinus. Methanol extract of Rheum undulatum L. root

Benzalacetone synthase (BAS) and chalcone synthase (CHS) are plant-specific type III polyketide synthases (PKSs) that share approximately 70% amino acid sequence identity. BAS catalyzes a one-step decarboxylative condensation of 4-coumaroyl-CoA with malonyl-CoA to produce a diketide benzalacetone,

Benzalacetone synthase (BAS) and chalcone synthase (CHS) are plant-specific type III polyketide synthases (PKSs), sharing 70% amino acid sequence identity and highly homologous overall protein structures. BAS catalyzes the decarboxylative coupling of 4-coumaroyl-CoA with malonyl-CoA to produce the

Aloesone synthase (ALS) and chalcone synthase (CHS) are plant-specific type III poyketide synthases sharing 62% amino acid sequence identity. ALS selects acetyl-CoA as a starter and carries out six successive condensations with malonyl-CoA to produce a heptaketide aloesone, whereas CHS catalyses
