The genome sequence of Lactobacillus sakei 23K has revealed that the species L. sakei harbors several genes involved in the catabolism of energy sources other than glucose in meat, such as glycerol, arginine, and nucleosides. In this study, a screening of 15 L. sakei strains revealed that arginine, inosine, and adenosine could be used as energy sources by all strains. However, no glycerol catab...

introduction: strength training has an important role in the exercise programs of normal individuals and athletes and it also has numerous benefits on the health of human body and spirit. one of the types of these exercise is eccentric resistance exercise which is associated with negative physiological changes. thus: this study examined the effects of a single bout of eccentric resistance exerc...

Pseudomonas putida S16 is an efficient degrader of nicotine. The complete genome of strain S16 (5,984,790 bp in length) includes genes related to catabolism of aromatic and heterocyclic compounds. The genes of enzymes in the core genome and a genomic island encode the proteins responsible for nicotine catabolism.

The absorption of radioactive cholesterol tended to be increased, and the catabolism of cholesterol detected by the decay of radioactive cholesterol in the serum after the intraperitoneal injection was delayed in ALR in comparison with normotensive WK rats. The reactive hypercholesterolemia in the ALR which had been selectively bred for a greater hypercholesterolemia was ascribed to the decreas...

Several strains have been reported to grow on 3-methyl-4-nitrophenol (3M4NP), the primary breakdown product of the excessively used insecticide fenitrothion. However, the microbial degradation of 3M4NP at molecular and biochemical levels remains unknown. Here, methyl-1,4-benzoquinone (MBQ) and methylhydroquinone (MHQ), rather than catechol proposed previously, were identified as the intermediat...

Catabolic mannopine (MOP) cyclase encoded by Ti or Ri plasmids lactonizes MOP to agropine (AGR). The gene of the octopine-type Ti plasmid pTi15955 encoding the catabolic MOP cyclase enzyme previously was localized to a 1.6-kb segment within a cosmid clone, pYDH208. A subclone containing only this region complemented the AGR catabolism-negative phenotype conferred by a derivative of the octopine...

The induction of polyamine catabolism by specific anti-tumour polyamine analogues has increased interest in the roles polyamine catabolism play in cell growth, death and response to various anti-tumour agents. The relatively recent finding of an inducible mammalian spermine oxidase (SMO/PAOh1), in addition to the two-step spermidine/spermine N(1)-acetyltransferanse (SSAT)/N(1)-acetylpolyamine o...

This study demonstrates that there is a 50% increase in the rate of folate catabolism in mice with ascitic tumours. The increased rate of catabolism coincided with the accumulation of ascitic fluid in the treated animals and a substantial increase in both the number and the weight of the malig nant cells, implying an active tumour. This suggests that the increased rate of catabolism was due eit...

Conjugation of recombinant human deoxyribonuclease I (rhDNase) to polyethylene glycol (PEG) 20 40 kDa was previously shown prolong the residence time rhDNase in lungs mice after pulmonary delivery while preserving its full enzymatic activity. This work aimed study fate native and PEGylated elucidate their biodistribution elimination pathways intratracheal instillation mice. In vivo fluorescence...
