The L-cysteine desulfhydrase of Escherichia coli.
The coenzyme function of pyridoxal-phosphate in cysteine desulfhydration and in the mechanistically similar serine and threonine dehydration (deamination) processes has been a subject of discussion in a number of recent publications (see, for example, Snell, 1952, and Braunstein and Shemyakin, 1953). A chemical model reaction has been proposed (Metzler and Snell, 1952). Evidence for pyridoxal-p...
متن کاملAn O-acetylserine(thiol)lyase homolog with L-cysteine desulfhydrase activity regulates cysteine homeostasis in Arabidopsis.
Cysteine (Cys) occupies a central position in plant metabolism due to its biochemical functions. Arabidopsis (Arabidopsis thaliana) cells contain different O-acetylserine(thiol)lyase (OASTL) enzymes that catalyze the biosynthesis of Cys. Because they are localized in the cytosol, plastids, and mitochondria, this results in multiple subcellular Cys pools. Much progress has been made on the most ...
متن کاملl-Cysteine-Assisted Synthesis of Urchin-Like γ-MnS and Its Lithium Storage Properties
MnS has been attracting more and more attentions in the fields of lithium ion batteries (LIBs) because of its high energy density and low voltage potential. In this paper, we present a simple method for the preparation of urchin-like γ-MnS microstructures using L-cysteine and MnCl2 · 4H2O as the starting materials. The urchin-like γ-MnS microstructures exhibit excellent cycling stability (823.4...

High-pressure polymorphism in L-cysteine: the crystal structures of L-cysteine-III and L-cysteine-IV.
The crystal structure of the orthorhombic phase of L-cysteine (hereafter L-cysteine-I) consists of chains of molecules linked via NH...O hydrogen bonds. The chains are linked into a layer by other NH...O hydrogen bonds, forming R4(4)(16) ring motifs. The layers are linked by further NH...O and disordered SH...S/SH...O interactions. The main effects of compression to 1.8 GPa are to contract void...
