Molecular weight, amino acid composition and physicochemical properties of the exocellular
The exocellular dd-carboxypeptidase–transpeptidase from Streptomyces R39 was purified to protein homogeneity and in milligram amounts. The isolated enzyme consisted of one polypeptide chain of molecular weight about 53300. Its amino acid composition and several physicochemical properties were determined and compared with those of the exo-cellular dd ...

Structure of the wall peptidoglycan of Streptomyces R39 and the specificity profile of its exocellular DD-carboxypeptidase-transpeptidase for peptide acceptors [PDF]
Benzylpenicillin and cephaloridine reacted with the exocellular dd-carboxypeptidase–transpeptidase from Streptomyces R39 to form equimolar and inactive antibiotic–enzyme complexes. At saturation, the molar ratio of chromogenic cephalosporin 87-312 to enzyme was 1.3:1, but this discrepancy might be due to a lack of accuracy in the measurement of the ...

Saharan striped polecats in agricultural landscapes use many burrows (30–35 per season), facilitated by sandy soils. Burrow sharing is rare and mainly occurs between males and females during mating. Habitat use shifts seasonally, reflecting disturbance and soil conditions. Maintaining stable sandy habitats may be critical for persistence.

Interaction of β-iodopenicillanate with the β-lactamases of Streptomyces albus G and Actinomadura R39 [PDF]
The beta-lactamases of Streptomyces albus G and Actinomadura R39 are inactivated by beta-iodopenicillanate. However, in contrast with the beta-lactamase I from Bacillus cereus, they also efficiently catalyse the hydrolysis of the inactivator; with the S. albus G enzyme, kcat.
