As society is becoming more reliant on fuels, a sustainable form of energy must be investigated. Another presiding issue the output cellulose left over from other plants that are used for biofuels, such as corn. However, microalgae, Chlamydomonas Reinhardtii, unicellular organism, an ideal source energy, there evidence it contains genes responsible encoding Cellulases, which allow degradation c...

Chlamydomonas reinhardtii is now becoming a useful model for the study of mitochondrial genetics in a photosynthetic organism. The small (15.8 kb) mitochondrial genome C. reinhardtii has been sequenced completely and all the genes have been identified. Several mutants inactivated in mitochondrial genes encoding components of the respiratory complexes I, III and IV have been characterized at the...

Linkage relationships were determined for six genes in Chlamydomonas reinhardtii: pyr, act, can-la, ey, y-1, and nic-7. Four of these were combined with five other genes to form linkage test strains.

Selenium (Se) deficiency is associated with the occurrence of many diseases. However, excessive Se supplementation, especially with inorganic Se, can result in toxicity. Selenoproteins are the major forms of Se in vivo to exert its biological function. Expression of those selenoproteins, especially with the application of a newly developed system, is thus very important for studying the me...

Systems level approaches to analyzing complex emergent behavior require quantitative characterization of alterations of behavior on both the microscale and macroscale. Here we consider the problem of cellular organization and describe a statistical methodology for quantitative comparison of the internal organization between different populations of similar physical objects, such as cells. This ...

O(2) irreversibly inactivates hydrogenase from Chlamydomonas reinhardi. The mechanism for the inactivation involves the reaction of one molecule of hydrogenase with one molecule of O(2) (or two oxygen atoms) in the transition complex of the rate-limiting step. The second order rate constant for this reaction is 190 atmospheres(-1) minute(-1) (1.4 x 10(5) molar(-1) minute(-1)). At levels above 0...

Carbonic anhydrases (CAs) are metalloenzymes that are omnipresent in nature. CAs catalyze the basic reaction of the reversible hydration of CO₂ to HCO₃- and H⁺ in all living organisms. Photosynthetic organisms contain six evolutionarily different classes of CAs, which are namely: α-CAs, β-CAs, γ-CAs, δ-CAs, ζ-CAs, and θ-CAs. Many of the photosynthetic organisms contain multiple isoforms of each...

The occurrence of calreticulin, the main Ca21 binding protein in the endoplasmic reticulum of eukaryotic cells, was investigated in the unicellular green alga Chlamydomonas reinhardtii Dangeard. The biochemical characterization of a diethylaminoethyl purified extract highlighted the presence, on SDSPAGE, of a 55-kDa protein that stained blue with the Stains All dye, a diagnostic feature of acid...

A methyltransferase from the green alga Chlamydomonas reinhardtii was identified and engineered for late-stage modifications of carbon skeleton terpenes. variant with three changes in amino acid sequence able to produce methylated derivatives linear terpenoids high selectivity by C-methylation an unactivated alkene. This opens new avenues modification scaffolds various applications, as demonstr...
