PROTEUS2: A Web Server for Comprehensive Protein Structure Prediction and Structure-Based Annotation
Download2008
Shrivistava, S., Berjanskii, M., Wishart, D.S., Cruz, J.A., Arndt, D., Montgomerie, S.
PROTEUS2 is a web server designed to support comprehensive protein structure prediction and structure-based annotation. PROTEUS2 accepts either single sequences (for directed studies) or multiple sequences (for whole proteome annotation) and predicts the secondary and, if possible, tertiary...

Purification and characterization of an anaerobically induced alanine aminotransferase from barley roots
Download1992
Alanine aminotransferase (AlaAT, EC 2.6.1.2) is an enzyme that is induced under anaerobic conditions in cereal roots. In barley (Hordeum vulgare L.) roots, there are a number of isoforms of AlaAT. We have identified the anaerobically induced isoform and have purified it to homogeneity. The...

Owttrim, George W., Colman, Brian.
Phosphoenolpyruvate (PEP) carboxylase (EC 4.1.1.31) was purified 100-fold from the cyanobacterium Coccochloris peniocystis with a yield of 10%. A single isozyme was found at all stages of purification, and activity of other beta-carboxylase enzymes was not detected. The apparent molecular weight...

One key issue for theory in stream ecology is how much stream flow can be changed while still maintaining an intact stream ecology, instream flow needs (IFNs); the study of determining IFNs is challenging due to the complex and dynamic nature of the interaction between the stream environment and...

Water resources worldwide require management to meet industrial, agricultural, and urban consumption needs. Management actions change the natural flow regime, which impacts the river ecosystem. Water managers are tasked with meeting water needs while mitigating ecosystem impacts. We develop...

Transient dynamics often differ drastically from the asymptotic dynamics of systems. In this paper we analyze transient dynamics in birth-jump metapopulations where dispersal occurs immediately after birth (e.g., via larval dispersal). We address the choice of appropriate norms as well as...

ReAS: Recovery of Ancestral Sequences for Transposable Elements from the Unassembled Reads of a Whole Genome Shotgun
Download2005
Ye, C., Wang, J., Li, S., Li, R., Wong, G.K.S., Ye, J., Yang, H., Han, Y., Yu, J.
We describe an algorithm, ReAS, to recover ancestral sequences for transposable elements (TEs) from the unassembled reads of a whole genome shotgun. The main assumptions are that these TEs must exist at high copy numbers across the genome and must not be so old that they are no longer...
