Characteristics of photodissociation at 193 nm of singly protonated peptides generated by matrix-assisted laser desorption ionization (MALDI)
Photodissociation (PD) at 193 nm of various singly protonated peptides was investigated. These include peptides with an arginine residue at the C-terminus, N-terminus, at both termini, inside the chain, and those...

Efficient and reliable calculation of rice-ramsperger—kassel-marcus unimolecular reaction rate constants for biopolymers: Modification of beyer-swinehart algorithm for degenerate vibrations
The Beyer-Swinehart (BS) algorithm, which calculates vibrational state density and sum, was modified for simultaneous treatment of degenerate vibrations. The modified algorithm was used in the grouped-frequenc...

Endogenous and Exogenous Calcium Involved in the Betulin Production from Submerged Culture of Phellinus linteus Induced by Hydrogen Sulfide
Using pharmacological and biochemical approaches, Ca2+ involved in the betulin production in mycelia of Phellinus linteus induced by hydrogen sulfide (H2S) were investigated. The results showed that 2 mM H2S dono...
