Reconstitution of prenyltransferase activity on nanodiscs by components of the rubber synthesis machinery of the Para rubber tree and guayule [PDF]

Scientific Reports, 2022
Natural rubber of the Para rubber tree (Hevea brasiliensis) is synthesized as a result of prenyltransferase activity. The proteins HRT1, HRT2, and HRBP have been identified as candidate components of the rubber biosynthetic machinery.

Rubber biosynthesis drives the biogenesis and development of rubber particles, the rubber-producing organelles. [PDF]

Plant Biotechnol J
Summary Rubber particles (RPs) are specialized organelles for the biosynthesis and storage of natural rubber in rubber‐producing plants. However, the mechanisms underlying the biogenesis and development of RPs remain unclear. In this study, two latex‐specific cis‐prenyltransferases (CPTs), TkCPT1 and TkCPT2, were identified in Taraxacum kok‐saghyz ...

Synergistic Potential of Argentatins A and B to Improve 5-Fluorouracil Cytotoxicity in Colorectal Cancer Cell Models. [PDF]

J Cell Mol Med
ABSTRACT Colorectal cancer is the third most commonly diagnosed cancer worldwide and the second most common cause of cancer‐related death in both men and women. Although a number of treatments are available to combat this malignancy, the antimetabolite 5‐fluorouracil has been the cornerstone of therapy since its synthesis in the 1950s.

Proteomic and Targeted Lipidomic Analyses of Fluid and Rigid Rubber Particle Membrane Domains in Guayule [PDF]

Plants
Rubber (cis-1,4-polyisoprene) is produced in cytosolic unilamellar vesicles called rubber particles (RPs), and the protein complex responsible for this synthesis, the rubber transferase (RTase), is embedded in, or tethered to, the membranes of these RPs.
