Functional characterization and structural insights of three cutinases from the ascomycete Fusarium verticillioides.

Cutinases are serine esterases that belong to the α/β hydrolases superfamily. The natural substrates for these enzymes are cutin and suberin, components of the plant cuticle, the first barrier in the defense system against pathogen invasion. It is well-reported that plant pathogens produce cutinases to facilitate infection.

Deep sequencing reveals differences in the transcriptional landscapes of fibers from two cultivated species of cotton.

Cotton (Gossypium) fiber is the most prevalent natural product used in the textile industry. The two major cultivated species, G. hirsutum (Gh) and G.

Identification of a second family of genes in Moniliophthora perniciosa, the causal agent of witches' broom disease in cacao, encoding necrosis-inducing proteins similar to cerato-platanins.

The hemibiotrophic basidiomycete Moniliophthora perniciosa is the causal agent of witches' broom disease in cacao. This is a dimorphic species, with monokaryotic hyphae during the biotrophic phase, which is converted to dikaryotic mycelia during the saprophytic phase. The infection in pod is characterized by the formation of hypertrophic and hyperplasic tissues in the biotrophic phase, which is followed by necrosis and complete degradation of the organ.

Biochemical and structural characterization of the hypoxanthine-guanine-xanthine phosphoribosyltransferase from Pyrococcus horikoshii.

The 6-oxopurine phosphoribosyltransferase (HPRT, EC 2.4.2.

Focal adhesion kinase mediates MEF2 and c-Jun activation by stretch: role in the activation of the cardiac hypertrophic genetic program.

Objective: We have previously reported that myocyte enhancer factor-2 (MEF2) transcription factors and c-Jun are rapidly activated by pressure overload and that these events are involved in the early activation of the myocardial hypertrophic genetic program. In this study, we investigated whether focal adhesion kinase (FAK) mediates the activation of MEF2 and c-Jun by mechanical stress in isolated neonatal rat ventricular myocytes (NRVMs).

Methods: NRVMs were subjected to cyclic stretch up to 4 h and studied by immunoblotting, reverse transcriptase-polymerase chain reaction, laser confocal analysis, and reporter gene and electrophoretic mobility shift assays.

The generation and utilization of a cancer-oriented representation of the human transcriptome by using expressed sequence tags.

Whereas genome sequencing defines the genetic potential of an organism, transcript sequencing defines the utilization of this potential and links the genome with most areas of biology. To exploit the information within the human genome in the fight against cancer, we have deposited some two million expressed sequence tags (ESTs) from human tumors and their corresponding normal tissues in the public databases. The data currently define approximately 23,500 genes, of which only approximately 1,250 are still represented only by ESTs.
