How can you use “cysteines” in a sentence? Here are some example sentences to help you improve your vocabulary:
The presence or absence of two features, the two pairs of cysteines in the 2X CXXC domain and the rhodanese-like domain, form the primary basis for differentiation between the four different protein structures among the sequences found in Table 1(Figure 2c).
These four highly conserved cysteines suggest that two disulfide bonds may be present on the extracellular surface of ORs.
The hyperthermophilic topoisomerase I from Thermotoga maritima has been shown to coordinate one Zn(II) with a unique tetracysteine motif Cys-X-Cys-X 16 -Cys-X-Cys but Zn(II) binding is not required for relaxation activity [ 33 ] . The sequence of this unique tetracysteine motifs is somewhat different from those present in other type IA topoisomerases in that the other tetracysteine motifs always had at least two amino acids separating the pairs of cysteines (Cys-X 2-11 -Cys), instead of just one amino acid (Cys-X-Cys) in T. maritima topoisomerase I [ 33 ] . Therefore the structure and function of the single Zn(II) binding motif in T. maritima may differ from the multiple Zn(II) binding motifs in E. coli topoisomerase I. Direct interaction between DNA and the T. maritima Zn(II) binding motif has not been demonstrated.
The importance of monitoring transient changes in cysteines is highlighted by the recent finding that oxidation of the Yap1 activator of antioxidant genes in the yeast
OxyR contains two critical cysteines that are oxidized to form an intramolecular disulfide bond when cells encounter peroxide stress (Zheng et al.
