The plant multigenic family of thiol peroxidases☆
Free Radical Biology and Medicine, 2005Thiol peroxidases are ubiquitous recently characterized heme-free peroxidases, which catalyze the reduction of peroxynitrites and of various peroxides by catalytic cysteine residues and thiol-containing proteins as reductants. In plants, five different classes can be distinguished, according to the number and the position of conserved catalytic ...

Distribution of the number of alleles in multigene families
Journal of Applied Probability, 1992The distribution of the number of alleles in samples from r chromosomes is studied. The stochastic model used includes gene conversion within chromosomes and mutation at loci on the chromosomes. A method is described for simulating the distribution of alleles and an algorithm given for computing lower bounds for the mean number of alleles ...

The human serum paraoxonase/arylesterase gene (PON1) is one member of a multigene family.
Genomics, 1996A physiological role for paraoxonase (PON1) is still uncertain, but it catalyzes the hydrolysis of toxic organophosphates. Evidence that the human genome contains two PON1-like genes, designated PON2 and PON3, is presented here.

The HSP70 multigene family of Caenorhabditis elegans
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19901. The heat shock response of the nematode Caenorhabditis elegans has been characterized. 2. There are at least nine genes in the hsp70 multigene family of C. elegans. 3. Five of the hsp70 genes have been characterized and assigned to one of at least three hsp70 gene subfamilies.

Structure and evolution of the apolipoprotein multigene family
Journal of Molecular Biology, 1986We present the complementary DNA and deduced amino acid sequence of rat apolipoprotein A-II (apoA-II), and the results of a detailed statistical analysis of the nucleotide and amino acid sequences of all the apolipoprotein gene sequences published to date: namely, those of human and rat apoA-I, apoA-II and apoE, rat apoA-IV, and human apoC-I, C-II and ...

A multigene family of Heteractis magnificalysins (HMgs).
Toxicon, 2008Sea anemones are passive predators. They use their specialized stinging cells (nematocysts) to immobilize any prey that blunders into them. A cnida fires, everting a tubule which delivers toxins that may stick to a prey. These toxins include neurotoxins, cytotoxins, cardiotoxins and haemolysins.

Evolution of the Spiroplasma P58 Multigene Family
Biochemical Genetics, 2007Spiroplasma citri and S. kunkelii are prokaryotic phytopathogens transmitted primarily by leafhopper vectors. S. citri BR3-3X was originally isolated from horseradish plants with brittle root disease (Fletcher et al., 1981). Extensive chromosomal rearrangement was found in one derivative of S.

Phylogenetics and Computational Biology of Multigene Families
2007This chapter introduces the study of the major evolutionary forces operating in large gene families. The reconstruction of duplication history and phylogenetic analysis provide an interpretative framework of the evolution of multigene families. We present here two case studies, the first coming from Eukaryotes (chemokine receptors) and the second from ...

Genetic Differentiation of Multigene Families [PDF]
, 1980 Let us consider a situation where a population was split into two identical ones and the two populations have been isolated thereafter. Let Ne be the effective population size of both new and original populations, i. e. the original population has doubled to give the two daughter populations. I shall here apply the simple model of double diffusion. Let

Murine Hox Genes — A Multigene Family
1988The embryonal development of higher organisms is conducted by a network of many different structural and regulatory gene functions whose complexity is yet poorly understood. Some genetic elements identified as being involved in specifying segment identity of the fruit fly Drosophila melanogaster are the homeotic genes (Ouweneel 1976).
