Glutenin amino acid sequences

Lew, E.J.-L., Kuzmicky D.D., and Kasarda, D.D. Characterization of low molecular weight glutenin subunits by reversed-phase high-performance liquid chromatography, sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and N-terminal amino acid sequencing. Cereal Chem., 69(5) 508-515, 1992. 

As shown in Table 15.15, the HMW subunits of glutenin are the only gluten proteins in which Gly (ca. 19%), and not Pro (ca. 12%), takes second place in the order of amino acids after Glx (ca. 36%). Furthermore, the proteins are characterized by the highest content of T)t (ca. 6%) and Thr (ca. 3.5%) and the lowest content of Phe (ca. 0.3%) and He (ca. 0.8%). In the N-ter-minal amino acid sequence presented in Table 15.16, the sequence EGEAS-RQLQC is valid for all known HMW subunits and varies only in position 6 (E, K, G). Erom the total sequences known until now, it can be deduced that the HMW subunits consist of three segments (A-C in Table 15.17). The N- and C-terminal segments...
