Transport of Lysine and Hydroxylysine in Streptococcus faecalis

Hydroxylysine metabolism in Streptococcus faecalis.

Replacement of Lysine by Hydroxylysine and Its Effects on Cell Lysis in Streptococcus faecalis.

Shockman, Gerald D. (Temple University, Philadelphia, Pa.), J. Stuart Thompson, and Margaret J. Conover. Replacement of lysine by hydroxylysine and its effects on cell lysis in Streptococcus faecalis. J. Bacteriol. 90:575-588. 1965.-Hydroxylysine was not significantly incorporated by Streptococcus faecalis ATCC 9790 or 8043 until exponential growth ceased as a result of lysine exhaustion. Uptak...

Streptococcus faecalis proton gradients and tetracycline transport.

The transport of chlortetracycline by Streptococcus faecalis is energy dependent. Addition of glucose to energy-depleted cells enhances both the transport rates and accumulation levels. Transport rates can be altered independently of glucose by treating cells with ionophores that increase or decrease the proton gradient. The transport of the antibiotic is linked only to the transmembrane pH dif...

Transport of aminophosphonic acids in Lactobacillus plantarum and Streptococcus faecalis.

Aminophosphonic acids analogous to glutamic acid, aspartic acid, alanine, and valine were actively accumulated by Lactobacillus plantarum. Uptake was dependent on the availability of glucose and, in all cases, the estimated intracellular concentrations substantially exceeded extracellular levels. During uptake, there was little metabolism of tritiated 2-amino-3-phosphonopropionic acid (APP), th...
