Báo cáo khoa học: Extrinsic proteins of photosystem II An intermediate member of the PsbQ protein family in red algal PS II
The oxygen-evolving photosystem II (PS II) complex of red algae contains four extrinsic proteins of 12 kDa, 20 kDa, 33 kDa and cytc-550, among which the 20 kDa protein is unique in that it is not found in other organisms.We cloned the gene for the 20-kDa protein from a red algaCyanidium caldarium. The gene consists of a leader sequence which can be divided into two parts: one for transfer across the plastid envelope and the other for transfer into thylakoid lumen, indicating that the gene is encoded by the nuclear genome....8 trang

Báo cáo khoa học: Kinetic mechanism for p38 MAP kinase a A partial rapid-equilibrium random-order ternary-complex mechanism for the phosphorylation of a protein substrate
p38 Mitogen-activated protein kinase alpha (p38 MAPKa) is a member of the MAPK family. It is activated by cellular stresses and has a number of cellular substrates whose coordinated regulation mediates inflammatory responses. In addition, it is a useful anti-inflammatory drug target that has a high specificity for Ser-Pro or Thr-Pro motifs in proteins and contains a number of transcription factors as well as protein kinases in its catalog of known substrates.15 trang

Báo cáo khoa học: The crystal structure of glucose-6-phosphate isomerase from Leishmania mexicana reveals novel active site features
Glucose-6-phosphate isomerase catalyzes the reversible aldose-ketose isomerization of D-glucose-6-phosphate to D-fructose-6-phosphate in glycolysis and gluconeogenesis, and in the recycling of hexose-6-phosphate in the pentose phosphate pathway. The unicellular protozoans,Trypan-osoma brucei, T. cruziandLeishmaniaspp., of the order Kinetoplastida are important human parasites responsible for African sleeping sickness, Chagas’ disease and leish-maniases, respectively. In these parasites, glycolysis is an important (and in some cases the only) metabolic pathway for ATP supply....8 trang

Báo cáo khoa học: Knock-out of the chloroplast-encoded PSI-J subunit of photosystem I in Nicotiana tabacum PSI-J is required for efficient electron transfer and stable accumulation of photosystem I
The plastid-encodedpsaJgene encodes a hydrophobic low-molecular-mass subunit of photosystem I (PSI) containing one transmembrane helix. Ho-moplastomic transformants with an inactivatedpsaJgene were devoid of PSI-J protein. The mutant plants were slightly smaller and paler than wild-type because of a 13% reduction in chlorophyll content per leaf area caused by an 20% reduction in PSI.13 trang

Báo cáo khoa học: Binding of cGMP to the transducin-activated cGMP phosphodiesterase, PDE6, initiates a large conformational change involved in its deactivation
Retinal photoreceptor phosphodiesterase (PDE6), a key enzyme for photo-transduction, consists of a catalytic subunit complex (Pab) and two inhibi-tory subunits (Pcs). Pabhas two noncatalytic cGMP-binding sites. Here, using bovine PDE preparations, we show the role of these cGMP-binding sites in PDE regulation.19 trang
