Expression, purification and preliminary crystallographic analysis of sucrose phosphate synthase (SPS) from Halothermothrix orenii.

چکیده
This is the first report of the crystallization of a sucrose phosphate synthase (SPS; EC 2.4.1.14). It also constitutes the first study of a sucrose phosphate synthase from a non-photosynthetic thermohalophilic anaerobic bacterium, Halothermothrix orenii. The purified recombinant spsA protein has been crystallized in the monoclinic space group C2, with unit-cell parameters a = 154.2, b = 47.9, c = 72.3 A, beta = 103.16 degrees, using the hanging-drop vapour-diffusion method. The crystal diffracts X-rays to a resolution limit of 3.01 A. Heavy-metal and halide-soaking trials are currently in progress to solve the structure.

Purification and preliminary characterization of sucrose-phosphate synthase using monoclonal antibodies.
Monoclonal antibodies specific for sucrose phosphate synthase (SPS; EC 2.4.1.14) have been obtained for the first time. Three independent clones have been isolated which inhibited spinach (Spinacia oleracea L.) leaf SPS activity and facilitated the enzyme purification by immunoprecipitation. All three clones were specific for the spinach enzyme but neither inhibited nor precipitated the SPS pre...
متن کاملCloning and characterization of the Cerasus humilis sucrose phosphate synthase gene (ChSPS1)
Sucrose is crucial to the growth and development of plants, and sucrose phosphate synthase (SPS) plays a key role in sucrose synthesis. To understand the genetic and molecular mechanisms of sucrose synthesis in Cerasus humilis, ChSPS1, a homologue of SPS, was cloned using RT-PCR. Sequence analysis showed that the open reading frame (ORF) sequence of ChSPS1 is 3174 bp in length, encoding a predi...
متن کاملExpression of a maize sucrose phosphate synthase in tomato alters leaf carbohydrate partitioning.
We isolated a complementary DNA sequence for the enzyme sucrose phosphate synthase (SPS) from maize utilizing a limited amino acid sequence. The 3509-bp cDNA encodes a 1068-amino acid polypeptide. The identity of the cDNA was confirmed by the ability of the cloned sequence to direct sucrose phosphate synthesis in Escherichia coli. Because no plant-specific factors were necessary for enzymatic a...
متن کاملIdentification and expression profile analysis of the sucrose phosphate synthase gene family in Litchi chinensis Sonn.
Sucrose phosphate synthase (SPS, EC 2.4.1.14) is a key enzyme that regulates sucrose biosynthesis in plants. SPS is encoded by different gene families which display differential expression patterns and functional divergence. Genome-wide identification and expression analyses of SPS gene families have been performed in Arabidopsis, rice, and sugarcane, but a comprehensive analysis of the SPS gen...
متن کاملCloning of a sucrose-phosphate synthase gene highly expressed in flowers from the tropical epiphytic orchid Oncidium Goldiana.
Sucrose-phosphate synthase (SPS) is one of the key regulatory enzymes in carbon assimilation and partitioning in plants. It plays a crucial role in the production of sucrose in photosynthetic cells. The cloning and expression analysis of a full-length cDNA encoding SPS from tropical epiphytic orchid hybrid Oncidium Goldiana are reported here. The cDNA designated as sps1 is 3820 bp in length wit...
