Plant Physiol
. 2000 Dec;
124(4):1678-96.
PMID: 11115885
The etioplast of dark-grown angiosperms is characterized by the prolamellar body (PLB) inner membrane, the absence of chlorophyll, and the accumulation of divinyl and monovinyl derivatives of protochlorophyll(ide) a [Pchl(ide)...

Armstrong G, Apel K, Rudiger W
Trends Plant Sci
. 2000 Jan;
5(1):40-4.
PMID: 10637661
Recent in vitro studies have led to speculation that a novel light-harvesting protochlorophyllide a/b-binding protein complex (LHPP) might exist in dark-grown angiosperms. Structurally, it has been suggested that LHPP consists...

FEBS Lett
. 1998 Aug;
432(3):117-22.
PMID: 9720908
The pore-forming colicins N and A require the porin, OmpF, in order to translocate across the outer membrane of Escherichia coli. We investigated the hypothesis that in vivo, colicins N...

Plant Cell
. 1998 Apr;
10(2):283-96.
PMID: 9490750
The etioplast plastid type of dark-grown angiosperms is defined by the accumulation of the chlorophyll (Chl) precursor protochlorophyllide (Pchlide) and the presence of the paracrystalline prolamellar body (PLB) membrane. Both...

. 1998 Feb;
275(2):171-6.
PMID: 9466900
Porins, such as Escherichia coli OmpF, provide the only reported example of a voltage-gated channel where the three-dimensional structure is known to high resolution. Mutations that affect voltage-gating are clustered...

PMID: 9351249
The structurally related light-dependent protochlorophyllide (Pchlide) oxidoreductases PORA and PORB mediate the only light-requiring step in chlorophyll (Chl) biosynthesis in higher plants. Correlative evidence suggests that some in vivo functions...

PMID: 9343362
Carotenoids represent one of the most widely distributed and structurally diverse classes of natural pigments, with important functions in photosynthesis, nutrition, and protection against photooxidative damage. In the eubacterial community,...
