Arginine Deiminase from Mycoplasma arthritidis
Hydrodynamic, chemical, and optical properties of arginine deiminase (EC 3.5.3.6) from Mycoplasma arthritidis are reported for the enzyme isolated from log phase cells. The s& +, and D’& values of the enzyme are 5.48 S and 5.87 x 10V7 cm’/s, respectively; the molecular weight is 87,300. Determination of the amino acid composition shows that about 45% of the residues are nonpolar. Another unique...
متن کاملGenome of Mycoplasma arthritidis.
The genomes of several species of mycoplasma have been sequenced. Most of these species rely on the glycolytic pathway for energy production, with the one exception of Ureaplasma, a species that breaks down urea as its principle source of acquiring energy. Several species, including as Mycoplasma arthritidis, are nonglycolytic and can use arginine as their source of energy. Described here are t...
متن کاملIdentification and purification of arginine deiminase that originated from Mycoplasma arginini.
A lymphocyte blastogenesis inhibitory factor, (LBIF), was purified from the culture supernatant of human histiocytic lymphoma U937 by fast protein liquid chromatography. In this study, we demonstrated, first, that LBIF originated from a mycoplasma, Mycoplasma arginini, infecting U937 cells, and second, that LBIF bore the arginine deiminase activity. The implication of in vivo immunosuppression ...
متن کاملCharacterization of the lysogenic bacteriophage MAV1 from Mycoplasma arthritidis.
The lysogenic bacteriophage MAV1, which is associated with the arthritogenicity of Mycoplasma arthritidis, was characterized. Several strains of M. arthritidis were examined for their ability to support growth of MAV1. A PFU assay was developed, and the sensitivity of phage to various chemical treatments was assayed. The most notable result was the resistance of MAV1 to proteinase K. The MAV1 g...
متن کاملApplication of monoclonal antibodies to detect intraocular mycoplasma antigens in Mycoplasma arthritidis-infected Sprague-Dawley rats.
Sprague-Dawley rats infected with Mycoplasma arthritidis by tail vein inoculation develop extensive disseminated joint inflammation, frequently accompanied by conjunctivitis and anterior uveitis. The intraocular inflammation is apparently directed at mycoplasmas localized within the stroma of the ciliary body, which have been detected with monoclonal antibodies by indirect immunofluorescence. T...
