Mycobacterium smegmatis Ku binds DNA without free ends.
Ku is central to the non-homologous end-joining pathway of double-strand-break repair in all three major domains of life, with eukaryotic homologues being associated with more diversified roles compared with prokaryotic and archaeal homologues. Ku has a conserved central 'ring-shaped' core domain. While prokaryotic homologues lack the N- and C-terminal domains that impart functional diversity t...
متن کاملMICROBIAL TRANSFORMATION OF CHOLESTEROL BY MYCOBACTERIUM SMEGMATIS
Mycobacterium smegmatis PTCC 1307 (CIP 73.26) was used as a microbial agent to produce androsta-1,4-diene-3,17-dione (ADD) and androst-4-ene-3,17-dione, two useful precursors in the synthesis of steroid drugs. The side chain of cholesterol, as the substrate, was selectively cleaved in the presence of five enzyme inhibitors. An intermediate structure with intact side chain, cholest-4-ene-3-one, ...
متن کاملC-terminal low-complexity sequence repeats of Mycobacterium smegmatis Ku modulate DNA binding
Ku protein is an integral component of the NHEJ (non-homologous end-joining) pathway of DSB (double-strand break) repair. Both eukaryotic and prokaryotic Ku homologues have been characterized and shown to bind DNA ends. A unique feature of Mycobacterium smegmatis Ku is its basic C-terminal tail that contains several lysine-rich low-complexity PAKKA repeats that are absent from homologues encode...
متن کاملsiderophore from Mycobacterium smegmatis
The extracellular siderophore from Mycobacterium smegmatis, exochelin MS, was isolated from iron-deficiently grown cultures and purified to > 98 % by a combination of ion-exchange chromatography and h.p.l.c. The material is unextractable into organic solvents, is basic (pI = 9.3-9.5), has a Amax. at 420 nm and a probable K. for Fe3+ of between 1025 and 1030. Its structure has been determined by...
متن کاملAmylooligosaccharides from Mycobacterium smegmatis.
In early stationary phase of growth, Mycobacterium smegmatis cultures accumulate amylooligosaccharides (alpha 1 leads to 4-glucooligosaccharides) up to the undecasaccharide. Although M. smegmatis also makes an acylated polymethylpolysaccharide that is predominantly and alpha 1 leads to 4-glucan, we conclude that these oligosaccharides are precursors of glycogen rather than lopopolysaccharide.
