Example sentences for: hxd
How can you use “hxd” in a sentence? Here are some example sentences to help you improve your vocabulary:
The multiple alignment contains at least three characteristic conserved motifs that center, respectively, at a HXD dyad near the amino terminus, a histidine towards the carboxyl terminus, and an arginine or lysine further downstream (Figure 1).
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).
The HXD dyad is located in a flexible loop that follows the first conserved strand and stacks with the sheet containing three of the core strands (Figures 2, 3).
The conserved HXD and the carboxy-terminal histidine coordinate Fe(II) that is directly involved in catalysis by these enzymes (Figure 2).
