Diversity oriented biosynthesis via accelerated evolution of modular gene clusters. [PDF]
, 2017 Erythromycin, avermectin and rapamycin are clinically useful polyketide natural products produced on modular polyketide synthase multienzymes by an assembly-line process in which each module of enzymes in turn specifies attachment of a particular ...

The Factors of the Classification of Protein Amino Acids [PDF]
This paper is published in GLASNIK of Montenegrin Academy of
Science and arts, 2000, 13, pp. 173-194, 2006 In this work it is shown that three pairs of the factors appear to be the key, i.e. main factors of a natural classification of protein (canonical) amino acids within the amino acid (genetic) code. First pair: the factors of the habit of an amino acid molecule (size and polarity).

Modeling of the formation of short-chain acids in propane flames [PDF]
arXiv, 2009 In order to better understand their potential formation in combustion systems, a detailed kinetic mechanism for the formation of short-chain monocarboxylic acids, formic (HCOOH), acetic (CH3COOH), propionic (C2H5COOH) and propenic (C2H3COOH)) acids, has been developed. Simulations of lean (equivalence ratios from 0.9 to 0.48) laminar premixed flames of

Discovery Of Copper Catalyst For New Chemical Polishing Acid On Superconducting Niobium [PDF]
arXiv, 2020 High field Q-slope (HFQS) seriously limits the high gradient performance of the buffered chemically polished (BCP) superconducting radio frequency (SRF) niobium cavities. The direct cause or mechanism is not yet fully understood. In our recent extensive data analysis, we concluded that the potential root cause could be nitrogen contamination on the ...

A thermodynamic basis for prebiotic amino acid synthesis and the nature of the first genetic code [PDF]
, 2009 Of the twenty amino acids used in proteins, ten were formed in Miller's atmospheric discharge experiments. The two other major proposed sources of prebiotic amino acid synthesis include formation in hydrothermal vents and delivery to Earth via meteorites.
