Sequences phylogenetic analysis

Mitochondrial CO II region was amplified by means of PCR, and the product was digested with restriction endonucleases (Ase I, Dra I, Hae III, Hinf I, Hpa II, Mva I, Pst I and Rsa I). Haplotypes were determined based on digestion-product electrophoretic patterns. To evaluate the phylogenetic relationships among haplotypes, one individual from each population locations was subjected to DNA sequencing. Phylogenetic analyses were conducted in PAUP and PHYLIP. 

Evolution of nucleic acid sequence Phylogenetic analyses often examine whether nucleotide substitutions are synonymous (not altering encoded amino acid) or nonsynonymous, and trace the history of gene- TABLE 18.6 Phylogenetic databases and utilities ... 

Histone Deacetylases (HDACs) catalyze the removal of the acetyl groups from lysines (see Fig. 1). Together with the HATs they are responsible for maintaining the level of histone acetylation throughout the genome. The family of HDAC proteins has been divided into four classes based on phylogenetic analysis and sequence comparison. HDACs of the classes I and II share the same Zn2+-based reaction and are evolutionary related. Class IV HDACs also possess a Zn2+-based reaction...

Ideally, one would gather a collection of full-length amino acid sequences for phylogenetic analysis. If all the sequences may be aligned over their full lengths, then the situation is simple and one may be able to carry out a fully automatic analysis. However, there are usually some complications, some of which are briefly covered in this section. 

Finally, it is worth noting the effect of these errors on the resulting phylogenetic analysis. If a complete outlier is included, it will tend to join the rest of the sequences on a long branch, as it will be only randomly related to each of them. These can be identified relatively easily when the final analysis is carried out. Sequences with frameshifts are harder...

A phylogenetic analysis of H4MPT-dependent enzymes reveals distinct archaeal and bacterial branches of the tree that are clearly related however, the results still do not resolve whether a common ancestor contained H4MPT-dependent enzymes or the methylotrophs acquired genes from the Archaea domain. Nonetheless, analysis of the genomic sequences from the Bacteria domain indicate that only the methylotrophic proteobacteria harbor HiMPT-dependent enzymes are consistent with lateral transfer from archaeal donors (Vorholt et al. 1999). 

A phylogenetic analysis of the catalase-peroxidase sequences (2) now extended to 20 available sequences, does not reveal any major subgroupings comparable to those in the catalase family. Whether this is because of the small number of sequences or because of the homogeneity of the enzymes will become evident as further sequences come available. As a result we will, for the time being, refer to the catalase-peroxidases as a single group of enzymes.
