The evolution of energy-transducing systems. Studies with an extremely halophilic archaebacterium [PDF]
The halobacterial ATPase was labeled with C-14-dicyclohexylcarbodiimide and subunit 2 of the enzyme was prepared by electroelution. Subunit 2 was cleaved by several chemical and enzymatic procedures for further preparation of peptides.

Biologic activity in a fragment of recombinant human interferon α [PDF]
To attempt to locate functionally important regions of the interferon (IFN) molecule, recombinant human IFN-α2 was subjected to proteolytic digestion. The bacterial proteinase thermolysin produced two major complementary fragments, HuIFN-α2-(1-110) and ...

Sac1p mediates the adenosine triphosphate transport into yeast endoplasmic reticulum that is required for protein translocation. [PDF]
Protein translocation into the yeast endoplasmic reticulum requires the transport of ATP into the lumen of this organelle. Microsomal ATP transport activity was reconstituted into proteoliposomes to characterize and identify the transporter protein.

Isolation and amino acid sequence analysis of a 4,000-dalton dynorphin from porcine pituitary [PDF]
A 4,000-dalton dynorphin was isolated from porcine pituitary. It has 32 amino acids (Mr = 3,986), with the previously described heptadecapeptide (now called dynorphin A) at its amino terminus and a related tridecapeptide, dynorphin B, at its carboxyl ...
