Words similar to metal-chelating

Example sentences for: metal-chelating

How can you use “metal-chelating” in a sentence? Here are some example sentences to help you improve your vocabulary:

Some of the RNA polymerases function as single-subunit proteins, whereas others form large complexes that consist of multiple, distinct subunits; however, in all known cases, the basic catalytic activity maps to a single polypeptide containing a characteristic metal-chelating active site [ 5 6 7 ] . Typically, active sites of polymerases contain acidic or polar residues, which coordinate divalent metal cations, most often Mg 2+.
Furthermore, some, but not all, members of the MJ0757 family contain an amino-terminal insertion of a small, metal-chelating module (Figure 5), which was used to improve the alignment with the E. coli TS [ 25], although this region was variable even within the MJ0757 family itself.
The high-scoring segment pairs (HSPs) detected in these searches aligned the highly conserved region of the RDRPs between the predicted strands 18 and 20, including the DbDGD motif, with the portion of the DDRP β' subunit sequence, which contains the metal-chelating active site, with a similar conserved motif, DxDGD.
Despite the lack of detectable sequence similarity to 2OG-Fe(II) dioxygenases, these proteins contain a conserved HXH motif and a carboxy-terminal histidine that appear to be equivalent to the metal-chelating HXD and carboxy-terminal histidine of the latter (see above).
