Bioenergetics is a field in biochemistry and cell biology that concerns energy flow through living systems. [1] This is an active area of biological research that includes the study of the transformation of energy in living organisms and the study of thousands of different cellular processes such as cellular respiration and the many other metabolic and enzymatic processes that lead to ...
Gene conversion is the process by which one DNA sequence replaces a homologous sequence such that the sequences become identical after the conversion. [1] Gene conversion can be either allelic , meaning that one allele of the same gene replaces another allele, or ectopic , meaning that one paralogous DNA sequence converts another.
Venenivibrio stagnispumantis gains energy by oxidizing hydrogen gas.. In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (e.g., hydrogen gas, hydrogen sulfide) or ferrous ions as a source of energy, rather than sunlight, as in ...
The mechanism for the conversion of CH 3 –S bond into methane involves a ternary complex of the enzyme, with the substituents forming a structure α 2 β 2 γ 2 . Within the complex, methyl coenzyme M and coenzyme B fit into a channel terminated by the axial site on nickel of the cofactor F430 . [ 6 ]
The Systems Biology Markup Language (SBML) is a representation format, based on XML, for communicating and storing computational models of biological processes. [1] It is a free and open standard with widespread software support and a community of users and developers.
Examples of degeneracy are found in the genetic code, when many different nucleotide sequences encode the same polypeptide; in protein folding, when different polypeptides fold to be structurally and functionally equivalent; in protein functions, when overlapping binding functions and similar catalytic specificities are observed; in metabolism, when multiple, parallel biosynthetic and ...
The book was the first to position cell biology as a central discipline for biology and medicine, and immediately became a landmark textbook. [3] It was written in intense collaborative sessions in which the authors lived together over periods of time, [3] organized by editor Miranda Robertson, then-Biology Editor of Nature. [4]
Synthetic biology (SynBio) is a multidisciplinary field of science that focuses on living systems and organisms, and it applies engineering principles to develop new biological parts, devices, and systems or to redesign existing systems found in nature.
