Complete (Ba-L) and truncated (Ba-S) forms of alpha-amylases from Bacillus subtilis X-23 were purified, and the amino- and carboxyl-terminal amino acid sequences of Ba-L and Ba-S were determined. The amino acid sequence deduced from the nucleotide sequence of the alpha-amylase gene indicated that Ba-S was produced from Ba-L by truncation of the 186 amino acid residues at the carboxyl-terminal r...

Human B-cell tumors have been established in athymic, BALB/c mice using the EBV-positive Burkitt lymphoma cell line Namalwa. One-hundred-one of 104 animals (97%) developed tumors 10-14 days following s.c. injection of a mixture of 20 x 10(6) Namalwa and 5 X 10(6) irradiated human fibrosarcoma (HT-1080) cells. Tumors developed at the site of injection and reached approximately 300 mm2 (product o...

R ECENTLY, synthetic angiotensin II has become available for study. Page, Helmer, Braun-Menendez, and co-workers have demonstrated that this compound represents the reaction product of renin on the ao-globulin hypertensinogen. Intensive pharmacological studies conducted by the Cleveland group' 4i 3 and the Swiss have verified these observations that synthetic angiotensin I I is identical with t...
