Sequence and Phylogenetic Analysis of FAD Synthetase.

An evolutionary analysis of the sequences available till now for FAD synthetases has been carried out. Several identical conserved residues have been observed along the sequences of all the FAD synthetases analyzed, which might correlate with role for these residues in the catalytic activity of the enzyme. Phylogenetic analysis shows that FAD synthetase sequences can be organized in two main clusters. One of them mainly contains temperature, pressure or pH resistant organisms, whereas in the other one organisms with pathogenic character can be found. © 2006 American Institute of Physics [ABSTRACT FROM AUTHOR]
