Corynebacterium glutamicum has two different Amt-type proteins. While AmtB has a low substrate affinity and is not saturable up to 3 mM methylammonium, AmtA has a high substrate affinity and mediates saturable, membrane potential-dependent transport, resulting in a high steady-state accumulation of methylammonium, even in the absence of metabolic trapping.

Corynebacterium diphtheriae has caused multiple isolated diphtheria cases in Malaysia over the years. Here, we report the first draft genome sequences of 15 Malaysia C. diphtheriae clinical isolates collected from the years 1981 to 2016.

The A-to-V mutation at position 111 (A111V) in the mechanosensitive channel NCgl1221 (MscCG) causes constitutive glutamate secretion in Corynebacterium glutamicum. Patch clamp experiments revealed that NCgl1221 (A111V) had a significantly smaller gating threshold than the wild-type counterpart and displayed strong hysteresis, suggesting that the gain-of-function mutation in the gating of NCgl12...

We report here the draft genome sequence of Corynebacterium pseudotuberculosis PA06, isolated from a subauricular abscess in an ovine host. C. pseudotuberculosis is a worldwide pathogen of small and large ruminants. The genome comprises 2,320,074 bp, with a G+C content of 52.2%, 2,195 coding sequences, 48 tRNAs, and three rRNAs.

Corynebacterium glutamicum mutant KY9707 was originally isolated for lysozyme-sensitivity, and showed temperature-sensitive growth. Two DNA fragments from a wild-type C. glutamicum chromosomal library suppressed the temperature-sensitivity of KY9707. These clones also rescued the lysozyme-sensitivity of KY9707, although partially. One of them encodes a protein of 382 amino acid residues, the N-...

urinary stones are prevalent and corynebacterium urealyticum, a urease-positive bacteria, is a frequent urinary tract pathogen. however, the association of this organism with urinary stones is not sufficiently studied in iran. this study was carried out to determine the prevalence of c. urealyticum in patients with urinary stones referred to the urology sections of tehran university of medical ...

Three draft and one complete genome sequence from strains isolated from urine and consistent with Corynebacterium CDC group F-1 were assembled and studied. Genome sizes ranged between 2.3 and 2.44 Mb, with G+C content between 60.4% and 60.7%.

A halotolerant, non-spore-forming actinobacterium was isolated from a soil sample from the west of China. The strain, designated YIM 70093(T) (=CCTCC AA 001024(T)=DSM 44683(T)), comprised Gram-positive, non-motile, diphtheroid and irregular rods. It grew in 0-25 % KCl (KCl could be substituted by NaCl or MgCl(2).6H(2)O), with optimum growth at 10 % KCl, and its optimal pH and cultivation temper...

Nocardia is a rare opportunistic agent, which may affect immunocompromised individuals causing lung infections and exceptionally infective endocarditis (IE). There are few reports of IE caused by Nocardia sp., usually involving biological prostheses but rarely in natural valves. Its accurate microbiological identification may be hampered by the similarity with Rhodococcus equi and Corynebacteri...
