mechanism of excretion of a bacterial proteinase: demonstration of two proteolytic enzymes produced by a sarcina strain (coccus p).a sarcina strain (coccus p) produces two proteolytic enzymes. one is found only extracellularly, is far more prevalent, and is actively excreted during exponential growth. it is the enzyme responsible for the known strong proteolytic activity of the cultures of this strain. a second protease is, however, produced which remains associated with the intact cells but is released by the protoplasts. the two enzymes appear unrelated in their derivation. calcium ions play an essential role in preventin ...19715107856
mechanism of excretion of a bacterial proteinase: factors controlling accumulation of the extracellular proteinase of a sarcina strain (coccus p).it has been known that the extracellular proteinase of coccus p is found only in cultures grown in the presence of ca(2+). it is now shown that this cation is required neither for synthesis, excretion, or activation of a zymogen nor as a prosthetic factor necessary for enzymatic activity. the only function of ca(2+) is to stabilize the active structure of the enzyme molecule, presumably by substituting for absence of s-s bridges. in the absence of ca(2+), the excreted proteinase undergoes rapid ...19715107857

microbial transformation of antibiotics: phosphorylation of clindamycin by streptomyces coelicolor müller.addition of clindamycin to whole-cell cultures of streptomyces coelicolor müller resulted in the loss of in vitro activity against organisms sensitive to clindamycin. incubation of such culture filtrates with alkaline phosphatase generated a biologically active material identified as clindamycin. fermentation broths containing inactivated clindamycin yielded clindamycin 3-phosphate, the structure of which was established by physical-chemical and enzymatic studies. clindamycin was phosphorylated ...19715166238

variation of type-b dna x-ray fiber diagrams with base composition.eight natural dnas of widely differing base composition have been studied by x-ray diffraction in fibers at high relative humidity. the resulting type b diffraction diagrams showed that all of the dnas had a 34-a pitch and 3.4-a interbase pair separation. however, the intensity distribution on the inner three layer lines was a strong function of the base content. in diffraction diagrams of very at-rich dna, the intensity of the first and third layer line was 2- or 3-times stronger than in the pa ...19734352977
