Abstract:
The megagametophytes of seeds of Pinus pinaster Ait. contain two types of oligomeric globulins of approximately 175 and 190 kDa that are comprised of 47-kDa and 27- and 22-kDa, monomers, respectively, joined by weak interactions. The 27- and 22-kDa components were purified and their N-terminal sequences determined. Both polypeptides were inherited as if they were coded by a single unit of recombination. The results obtained suggest that these two polypeptides originate from a single protein that undergoes proteolytic processing. The characteristics of this P. pinaster globulin indicate that it is a member of the 7S globulin family of seed storage proteins.

02:21Globular and Fibrous Proteins
Globular proteins are also known as spheroproteins and typically are approximately round in shape. They contain a mix of amino acid types and contain differing sequences in their primary structures. Globular proteins have many different functions, such as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be...
