(1992)The major heat shock proteins from Thiobacillus ferrooxidans were identified as DnaK and GroEL equivalents by Western blotting and analysis of the N-terminal amino acid sequence of spots isolated from dried 2-D polyacrylamide ...
-
(1992)Two forms of ATP-diphosphohydrolase were identified in Solanum tuberosum tuber var. Ultimus. Their hydrolytic activity ratios (ATPase/ADPase) were over 10 for form A and 1 for form B. In the potato tuber homogenate the ...
