Molecular evolution and optimization
Antonie van Leeuwenhoek, 1997Microbial populations (and life) not only evolve, they optimize. The transition from a random, unorganized, lifeless Earth to the present situation, where the Earth is virtually covered with nucleic acids and diverse and complex species, required numerous molecular changes and the integration of metabolic pathways over billions of years.

Journal of Theoretical Biology, 1992
The exciting results published by Scott & Smith (1990), Devlin et al. (1990), and Tuerk & Gold (1990) in Science; Cwirla et al., in the Proceedings of the National Academy of Sciences of the U.S.A. (1990) ; and Ellington & Szostak in Nature, London (1990), are the next developments in a new era in biotechnology: applied molecular evolution.

Molecular evolution in bacteria
Antonie van Leeuwenhoek, 1995Recent advances in microbiology and molecular biology have a unifying influence on our understanding of genetic diversity/similarity and evolutionary relationships in microorganisms. This article attempts to unify information from diverse areas such as microbiology, molecular biology, microbial physiology, clay crystal genes, metals-microbe-clay ...

General and Comparative Endocrinology, 2001
Leptin, a hormone produced mainly by adipocytes, is involved in the regulation of food intake, metabolism, and reproduction. The objective of this study was to determine the evolutionary relationships of leptin genes. Partial nucleotide sequences of leptin were cloned and sequenced from six mammalian species: large hairy armadillo (Chaetophractus ...

The molecular evolution of development
BioEssays, 1998Morphological differences between species, from simple single-character differences to large-scale variation in body plans, can be traced to changes in the timing and location of developmental events. This has led to a growing interest in understanding the genetic basis behind the evolution of developmental systems.

Molecular Evolution of Proteasomes
2002Proteasomes are large, multisubunit proteases that are found, in one form or another, in all domains of life and play a critical role in intracellular protein degradation. Although they have substantial structural similarity, the proteasomes of bacteria, archaea, and eukaryotes show many differences in architecture and subunit composition. This article

Annual Review of Ecology and Systematics, 1986
Many patterns in the evolution of proteins and DNA are now well established and have been adequately reviewed in recent years (23, 37, 38, 52, 55, 61, 73). However, there are several gaps in our understanding of the process of molecular evolution, the most conspicuous of which is our ignorance of the forces responsible for most of the evolution of DNA ...

Molecular Evolution of hisB Genes
Journal of Molecular Evolution, 2004The sixth and eighth steps of histidine biosynthesis are catalyzed by an imidazole glycerol-phosphate (IGP) dehydratase (EC 4.2.1.19) and by a histidinol-phosphate (HOL-P) phosphatase (EC 3.1.3.15), respectively. In the enterobacteria, in Campylobacter jejuni and in Xylella/Xanthomonas the two activities are associated with a single bifunctional ...

Molecular evolution of proglucagon
Regulatory Peptides, 2001The vertebrate proglucagon gene encodes glucagon, and the two glucagon-like peptides GLP-1 and GLP-2. To better understand the origin and diversification of the distinct hormonal roles of the three glucagon-like sequences encoded by the proglucagon gene, we have examined the evolution of this gene.
