Two Different Chalcone Synthase Activities from Spinach
Chalcone synthase activity was found in enzyme preparations from spinach. In homogenates of young leaves two different activities of the enzyme could be separated by DEAE-ion exchange chromatography and chromatofocusing. Both activities formed naringenin with [2-14C] malonyl- CoA and 4-coumaroyl-CoA as substrates. They exhibited only slight differences

Quinolones are valuable scaffolds for drug discovery but are rare in nature. Here, we show that two fungal enzymes, AthePKS and FerePKS, can generate 2‐quinolones and two additional heteroaromatic scaffolds. Using AthePKS, we designed an artificial enzymatic cascade towards an antimicrobial quinolone from a simple precursor and implemented it in E ...

Analysis of Flavanone 3-Hydroxylase in Arabidopsis Seedlings (Coordinate Regulation with Chalcone Synthase and Chalcone Isomerase) [PDF]
Abstract A genomic clone encoding flavanone 3-hydroxylase (F3H) was isolated from Arabidopsis thaliana. The deduced amino acid sequence is 72 to 94% identical to all previously reported F3H proteins. Low-stringency DNA blot analysis indicated that F3H is encoded by a single gene in Arabidopsis.

ABSTRACT Alfalfa (Medicago sativa L.) is known as the ‘King of Forage’ because of its high protein content and excellent palatability. Alfalfa productivity is adversely affected in cold regions with saline‐alkali soils. However, the mechanisms underlying the response of alfalfa to combined saline‐alkali and low‐temperature stress under field conditions

Studies have shown that abundant and various flavonoids accumulate in chili pepper (Capsicum), but there are few reports on the genes that govern chili pepper flavonoid biosynthesis. Here, we report the comprehensive identification of genes encoding type

ABSTRACT Anthocyanins, a group of secondary metabolites synthesised in the phenylpropanoid pathway, largely determine the peel colour of fleshy fruits, but it is not known if their synthesis is linked to vacuolar malate accumulation that underlies fruit acidity.

ABSTRACT Salvianolic acid is the main active component of Salvia miltiorrhiza and holds significant value in the clinical treatment of myocardial ischemia and hypoxia. Previous studies have shown that salicylic acid (SA) can significantly promote the accumulation of salvianolic acid, but its molecular mechanism remains incompletely understood.
