A small multigene family encodes 4-coumarate:CoA ligases (4CLs) catalyzing the CoA ligation of hydroxycinnamic acids, a branch point step directing metabolites to a flavonoid or monolignol pathway. In the present study, we examined the effect of antisense Populus tremuloides 4CL (Pt4CL1) to the lignin and soluble phenolic compound composition of silver birch (Betula pendula) Pt4CL1a lines in co...
ریحان (ocimum basilicum)، گیاهی علفی و یکساله از تیره نعناع است که به عنوان یک گیاه دارویی مهم برای بیماری هایی چون سردرد، سرفه، زگیل، کرم روده و نارسایی های کلیوی در ایران مورد استفاده است. اسانس ریحان به طور عمده شامل ترکیبات فنیل پروپانوئیدی است که مسیر بیوسنتز این ترکیبات از مسیر شیکمات می گذرد و مهمترین ترکیبات آنها شامل چاویکول، متیل چاویکول، اوژنول، متیل اوژنول، سینامات و المیسین می باشن...
The cholic acid CoA ligase activity of rat liver was quantitatively inactivated by proteolysis with pronase, chymotrypsin, subtilisin, or proteinase K in intact microsomal vesicles. Under the conditions employed, less than 14% of the lumenal mannose-6-phosphate phosphatase activity was lost, and the mannose-6-phosphate phosphatase activity remained highly latent. After microsomal integrity was ...
Lonicera macranthoides Hand.-Mazz (L. macranthoides) is a medicinal herb that is widely distributed in southern China. The biosynthetic and metabolic pathways for a core secondary metabolite in L. macranthoides, chlorogenic acid (CGA), have been elucidated in many species. However, the mechanisms of CGA biosynthesis and the related gene regulatory network in L. macranthoides are still not well ...
The different topology of palmitoyl-CoA ligase (on the cytoplasmic surface) and of lignoceroyl-CoA ligase (on the luminal surface) in peroxisomal membranes suggests that these fatty acids may be transported in different form through the peroxisomal membrane (Lazo, O., Contreras, M., and Singh, I. (1990) Biochemistry 29, 3981-3986), and this differential transport may account for deficient oxida...
BACKGROUND Oats contain hydroxycinnamoyl anthranilates, also named avenanthramides (Avn), which have beneficial health properties because of their antioxidant, anti-inflammatory, and antiproliferative effects. The microbial production of hydroxycinnamoyl anthranilates is an eco-friendly alternative to chemical synthesis or purification from plant sources. We recently demonstrated in yeast (Sacc...
4-Chlorobenzoate:coenzyme A ligase (4-CBA:CoA ligase) catalyzes the first step of the 4-CBA degradation pathway of Pseudomonas sp. strain CBS3. In this reaction, 4-CBA-CoA thioester synthesis is coupled to ATP cleavage. The studies described in this paper examine the intermediacy of 4-chlorobenzoyl-adenosine 5'phosphate diester (4-CBA-AMP) in the ligase reaction. The 4-CBA-AMP adduct was isolat...
Naturally occurring α-pyrones with biological activities are mostly synthesised by polyketide synthases (PKSs) via iterative decarboxylative Claisen condensation steps. Remarkably, we found that some enzymes related to the fatty acid β-oxidation pathway in Escherichia coli, namely CoA ligase FadD and thiolases FadA FadI, can synthesise styrylpyrones phenylpropionic acids vivo. The two directly ...
We have examined the ability of HepG2 human hepatoblastoma cells and 7800 C1 Morris rat hepatoma cells to convert 3 alpha, 7 alpha, 12 alpha-trihydroxy-5 beta-cholestanoic acid (THCA) and 3 alpha, 7 alpha-dihydroxy-5 beta-cholestanoic acid (DHCA) to cholic acid and chenodeoxycholic acid, respectively. Cell extracts from both these cell lines could neither form cholic acid from THCA nor from the...
