Two distinct cDNA clones encoding carbonic anhydrase (CA) were isolated from an Arabidopsis thaliana lambda YES library. One of these clones, CA1, encodes a 36.1-kD polypeptide and is essentially the same as a previously reported Arabidopsis CA cDNA (C.A. Raines, P.R. Horsnell, C. Holder, J.C. Lloyd
The procedure of isolating the thylakoids and the thylakoid membrane fragments enriched with either photosystem I or photosystem II (PSI- and PSII-membranes) from Arabidopsis thaliana leaves was developed. It differed from the one used with pea and spinach in durations of detergent treatment and
We have cloned and overexpressed a truncated, recombinant form of beta-carbonic anhydrase from Arabidopsis thaliana. The wild-type enzyme and two site-directed variants, H216N and Y212F, have been kinetically characterized both at steady state by stopped-flow spectrophotometry and at chemical
The expression of genes of two carbonic anhydrases (CA) belonging to the α-family, α-CA2 and α-CA4 (according to the nomenclature in N. Fabre et al. (2007) Plant Cell Environ., 30, 617-629), was studied in arabidopsis (Arabidopsis thaliana, var. Columbia) leaves. The expression of the At2g28210 gene
Changes in expression levels of genes encoding carbonic anhydrases α-CA1, α-CA2, α-CA4, β-CA1, β-CA2, β-CA3, β-CA4, β-CA5, and β-CA6 in Arabidopsis thaliana leaves after light increase from 80 to 400 µmol PAR quanta·m-2·s-1 were investigated under short day (8 h) and long day (16 h) photoperiods.
We have cloned and overexpressed a variant of Arabidopsis thaliana beta-carbonic anhydrase (Q158A) that deletes the functional equivalent of the backbone amide NH of Thr-199 in human alpha-carbonic anhydrase II. The latter residue is hypothesized to be important in catalyzing the rate of CO(2)(-)
UNASSIGNED
Red alga, Gracilariopsis chorda, contains seven carbonic anhydrases that can be grouped into α-, β- and γ-classes. Carbonic anhydrases (CAHs) are metalloenzymes that catalyze the reversible hydration of CO2. These enzymes are present in all living organisms and play roles in various
A full-length cDNA clone encoding carbonic anhydrase was isolated from an Arabidopsis thaliana (Columbia) leaf library. Comparison of the derived amino acid sequence obtained from this clone with those of pea and spinach reveals a considerable degree of identity. The carbonic anhydrase cDNA was used
BACKGROUND
The Arabidopsis CAH1 alpha-type carbonic anhydrase is one of the few plant proteins known to be targeted to the chloroplast through the secretory pathway. CAH1 is post-translationally modified at several residues by the attachment of N-glycans, resulting in a mature protein harbouring
The NADH-ubiquinone oxidoreductase complex (complex I) (EC 1.6.5.3) is the main entrance site of electrons into the respiratory chain. In a variety of eukaryotic organisms, except animals and fungi (Opisthokonta), it contains an extra domain comprising trimers of putative γ-carbonic anhydrases,
"Gamma-type carbonic anhydrase-like" (CAL) proteins form part of complex I in plants. Together with "gamma carbonic anhydrase" (CA) proteins they form an extra domain which is attached to the membrane arm of complex I on its matrix exposed side. In Arabidopsis two CAL and three CA proteins are
Complex I (NADH:ubiquinone oxidoreductase) is the entry point for electrons into the respiratory electron transport chain; therefore, it plays a central role in cellular energy metabolism. Complex I from different organisms has a similar basic structure. However, an extra structural module, referred
A proteomic study was conducted to investigate physiological factors affecting feeding behaviour by larvae of the insect, Plutella xylostella, on herbivore-susceptible and herbivore-resistant Arabidopsis thaliana. The leaves of 162 recombinant inbred lines (Rils) were screened to detect genotypes
