Abstract
-
Formaldehyde is a compound which is believed to have had a role in evolutionary
processes. On the other hand, the (methyl)glyoxalase pathway is a route being
present in all biological organisms whereas its function has not yet been
recognized in the biochemical machinery. In this article it is raised that
(methyl)glyoxalase path might have functioned as a bridge between formose and
archaic reductive citric acid cycles in surface metabolists at the early stage
of evolution. According to the theory, formaldehyde was essential for the
mentioned system as a raw molecule. Based on thermodynamic calculations a simple
way of regulation is also shown. The simplicity of the theory may be in a good
agreement with and an explanation of why the (methyl)glyoxalase system is of
ubiquitous nature.
