Example sentences for: ec-

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

  • Ec-MoeB, Mt-MoeBR, Pa-MoeB, Pa-MoeBR, and Sc-MoeBR all contain two pairs of cysteine residues, each arranged in a CXXC motif and spaced 68-70 residues apart, like those in ThiF proteins (arrows in Figures 2cand 3).

  • All 12 sequences in this region have high similarity to the derived consensus sequence GXGXXG(7X)A(SX)GXGXXG(4X)D(9X)R, which defines a nucleotide binding motif [ 16 25 ] . In addition, all sequences have five residues, or conservative substitutions in the case of Pa-MoeB, shown to participate in the adenylation reaction catalyzed by Ec-MoeB (Figure 3) [ 7 ] . The fact that such high similarities are retained in the ThiF coding region across three bacterial divisions suggests that this domain functions more or less autonomously.

  • All of the predicted amino acid sequences except Ec-MoeB, Mlo-MoeZdR, and Pa-MoeB also have C-terminal similarity (BLAST E value < 1 -12) to a rhodanese-like domain (Pfam00581) (Figure 2c, Table 2) [ 26 ] . Rhodanese, a thiosulfate:cyanide sulfurtransferase (EC 2.8.

  • MoeBR has the ThiF and 2X CXXC domains configured like MoeB but includes an N-terminal rhodanese-like domain, the polyproline motif, and has a Y substitution at position 155 (Ec-MoeB numbering).

  • MoeB, exemplified by Ec-MoeB, and MoeBR, exemplified by cnxF of Aspergillis nidulans [ 16 ] , participate in the synthesis of MPT-Mo as MSAEs.
