Parthenogenesis doubles the rate of amino acid substitution in whiptail mitochondria

Evolution, 2022
Sexual reproduction is ubiquitous in the natural world, suggesting that sex must have extensive benefits to overcome the cost of males compared to asexual reproduction. One hypothesized advantage of sex with strong theoretical support is that sex plays a role in removing deleterious mutations from the genome.

Double amino acid - a novel molecule enabling peptide interpenetrating structures

Chemical Physics Letters, 2014
Peptide chains might be linked with one another using various external bifunctional molecules. We postulate an existence of a novel molecule termed ‘double amino acid’ containing four functional groups connected to one C atom ((NH2)2C(COOH)2). Using correlated ab initio approach (QCISD and MP2 methods) we provide its structure, simulated IR spectrum ...

Immobilized Double-Racemase Hydantoinase Process for L-Amino Acid Production

2021
Protein immobilization is proving to be an environmentally friendly strategy for manufacturing biochemicals at high yields and low production costs. This work describes the optimization of the so-called “double-racemase hydantoinase process,” a system of four enzymes used to produce optically pure L-amino acids from a racemic mixture of hydantoins ...
