The phrase "a chains" is not correct in written English.
It should be "a chain" if referring to a single chain or "chains" if referring to multiple chains without the article "a."
Example: "He wore a chain around his neck."
Alternatives: "a series of chains" or "one chain."
Both of the two A chains from B. flaviceps are made up of 119 amino acids and comprise 15 cysteine residues, while the A chains of β-Bgt from other Bungarus species including B. candidus comprise 13 cysteine residues.
However, when the A chains are grafted to a surface, only limited amounts of B can be solubilized into this grafted shell due to the conformational constraints.
In general, the model predicts that solubilization is favoured when the B chains are small and the A chains are large and initially exist in a thin shell layer.
Exported ERAD substrates are normally targeted for ubiqutin-dependent proteasomal degradation, but the A chains of ER-translocating toxins have few lysine residues for ubiquitin conjugation and thus effectively avoid degradation by the 26S proteasome [4] [7].
The abundance of short A chains of DP 6 12 probably determines the starch crystalline allomorph [ 31].
The deduced amino acid sequence of rbp shows weak similarity to the A chains of the Shiga-like toxins SLT-1 and SLT-2 from Escherichia coli.
A novel efficient metal-free sensitizer CVTC-H-CVTP containing asymmetric double D-π-A chains was designed and synthesized for application in dye-sensitized solar cells (DSSCs).
The reactivity spectrum of HCA2 comprises all HLA-A chains (except HLA-A24), as well as some HLA-B, HLA-C, HLA-E, HLA-F and HLA-G chains.
The results using CHST11 siRNA further suggest that among the chondroitin sulfotransferases tested, CHST11 expression has a rate limiting role in constructing both CS-A chains and P-selectin ligands on MDA-MB-231 cells.
HC10 reacts with HLA-B and HLA-C heavy chains and some HLA-A chains (HLA-A10, HLA-A28, HLA-A29, HLA-A30, HLA-A31, HLA-A32, HLA-A33) [ 31].
Both A-chains have mostly well-defined electron density with very few problems in their interpretation.
