Summary : FT is a tool written in C++, which implements the Fourier analysis method to locate periodicities in aminoacid or DNA sequences. It is provided for free public use on a WWW server with a Java interface. Availability : The server address is http://o2.db. uoa.gr/FT Contact : [email protected]

Bovine and human serum albumins catalyze the aldol reaction of aromatic aldehyedes and acetone, with saturation kinetics and moderate and opposite enantioselectivity. The reaction occurs at the binding site in domain IIa, and is inhibited by warfarin. Kinetic data are consistent with an enamine mechanism. The activity is conserved in a 103 aminoacid peptide derived from the albumin sequence.

A technology capable of sequencing individual protein molecules would revolutionize our understanding biological processes. Nanopore can analyze single heteropolymer such as DNA by measuring the ionic current flowing through a nanometer hole made in an electrically insulating membrane. This is sensitive to monomer sequence. However, proteins are remarkably complex and identifying residue change...

The presence of hydroxyproline, and the determination of the ratio of the secondary amino acids proline to hydroxyproline, in amino acid hydrolysates specifically identifies collagen and collagen peptides. o-Phthalaldehyde, and then 9-fluorenylmethyl chloroformate, were used to carry out sequential prederivatization of amino acid hydrolysates in an in-line high-performance liquid chromatography...
