periplasm/thylakoid lumen and a short domain in the cyto-plasm/stroma (that of TatB being larger than TatA). The next gene in the tat operon, tatC is also critical for Tat-dependent export and E. coli cells disrupted in this gene are completely defective in the Tat export pathway (17).


The chloroplast compartment enclosed by the thylakoid membrane, the “lumen,” is poorly characterized. The major aims of this work were to design a procedure for the isolation of the thylakoid lumen which could be generally used to characterize lumenal proteins.

The major aims of this work were to design a procedure for the isolation of the thylakoid lumen which could be generally used to characterize lumenal proteins. The preparation was a stepwise procedure in which thylakoid membranes were isolated from intact chloroplasts. 2020-12-01 The thylakoid lumen is a continuous aqueous phase enclosed by the thylakoid membrane. It plays an important role for photophosphorylation during photosynthesis . During the light-dependent reaction, protons are pumped across the thylakoid membrane into the lumen making it acidic down to pH 4. The thylakoid lumen, a dynamic part of the photosynthetic process Research project The beautiful architecture of the thylakoid network is a distinguishing characteristic of the chloroplast of higher plants. The thylakoid lumen represents a continuous exoplasmic cellular space that is poorly characterized compared with the other chloroplast compartments.

A large fraction of the luminal volume of the granal thylakoids is occupied by the oxygen-evolving complex of photosystem II. Electron microscopy data we obtained on dark- and light-adapted Arabidopsis thylakoids indicate that the granal thylakoid lumen significantly expands in the light.

The thylakoid lumen has historically been considered a vacant compartment exclusively used to accommodate the evolution of oxygen in photosynthesis. Here, we describe a method for isolating the stromal, the thylakoid membrane, and the thylakoid lumen subchloroplast fractions from Arabidopsis thaliana leaf material. All three fractions can be isolated sequentially from the same plant material in a single day preparation. thylakoid membrane system inside the chloroplasts. In particular, the structure of the stacked grana area of thylakoid membranes is highly dynamic, changing in response to different environmental cues such as light intensity.

Thylakoid lumen

There is a total of three layers that are needed to be crossed while traveling from the cytoplasm to the thylakoid lumen. 2017-04-23 2005-04-25 Thylakoid lumen: lt;div class="hatnote"|>"Granum" redirects here.

[See accompanying illustration at right.] The electron transport chain moves protons across the thylakoid membrane into the lumen.

3c). Under medium light intensities, a swelling of the thylakoid lumen was observed that alleviates steric restrictions in grana thylakoids for the electron carrier plastocyanin caused by lumenal protrusions of PSII (Kirchhoff et al. 2011).
