Background Human gut bacteria can synthesize proteinogenic amino acids and produce a
range of metabolites via protein fermentation, some known to exert beneficial or harmful …

In bacteria, more than half of the genes in the genome are organized in operons. In contrast,
in eukaryotes, functionally related genes are usually dispersed across the genome. There …

Beneficial microbes and probiotic species, such as Lactobacillus reuteri, produce
biologically active compounds that can modulate host mucosal immunity. Previously …

Streptococcus mutans is the leading cause of dental caries (tooth decay) worldwide and is
considered to be the most cariogenic of all of the oral streptococci. The genome of S. mutans …

Tremendous chemical diversity is the hallmark of plants and is supported by highly complex
biochemical machinery. Plant metabolic enzymes originated and were transferred from …

Sequence-Evolution-Function is an introduction to the computational approaches that play a
critical role in the emerging new branch of biology known as functional genomics. The book …
