Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) is a critical protein for photosynthesis. With small subunits, RBCSs catalyze the fixation of CO2 onto ribulose-1,5-bisphosphate (RuBP).

ZZE-Configuration of chromophore ß-153 in C-phycocyanin from Mastigocladus laminosus [PDF]
The photochemistry of C-phycocyanin has been studied after denaturation in the dark. It shows an irreversible reaction which has characteristics of a Ζ,Ζ,Ε- to Z,Z,Z-isomerization of dihydrobilins. Its amplitude depends on the reaction conditions, with

Rubisco Extraction and Purification from Diatoms
This protocol describes a method to extract ribulose-1,5-bisphosphate carboxylase oxygenase (Rubisco) from diatoms (Bacillariophyta) to determine catalytic performance.

Metabolic and molecular events occurring during chromoplast biogenesis [PDF]
Chromoplasts are nonphotosynthetic plastids that accumulate carotenoids. They derive from other plastid forms, mostly chloroplasts. The biochemical events responsible for the interconversion of one plastid form into another are poorly documented. However,

Protein transport in intact, purified pea etioplasts [PDF]
We have developed a method to isolate intact, purified pea etioplasts. These etioplasts were capable of recognizing, transporting, and processing the precursor form of the small subunit of the ribulose-1,5-bisphosphate carboxylase, a protein which is not

Climate changes severely influence photosynthetic activity of plants. Studies on the combined effect of drought and heat stress on photosynthesis, pigments, and xanthophyll cycle particularly in alfalfa (Medicago sativa L.) are limited.

A Chlamydomonas reinhardtii RuBisCO-less mutant, ΔrbcL, was used to study carbohydrate metabolism without fixation of atmospheric carbon. The regulatory mechanism(s) that control linear electron flow, known as “photosynthetic control,” are amplified in ...

Rubisco catalytic properties and temperature response in crops. [PDF]
Rubisco catalytic traits and their thermal dependence are two major factors limiting the CO2 assimilation potential of plants. In this study, we present the profile of Rubisco kinetics for twenty crop species at three different temperatures.

Diffusive and Metabolic Constraints to Photosynthesis in Quinoa during Drought and Salt Stress
Quinoa (Chenopodium quinoa Willd.) has been proposed as a hardy alternative to traditional grain crops in areas with warm-to-hot climates that are likely to experience increased drought and salt stress in the future.
