摘要：

Streptomyces clavuligerus was able to accumulate proline intracellularly throughout a wide range of external proline concentrations. Kinetic analysis of proline uptake indicated that this phenomenon is mediated by two saturable systems. One of them was a high-affinity system (Km = 11 μM), with low uptake capacity and specific for proline. The second system had lower affinity for proline (Krmm = 10.2 mM), higher uptake capacity, and was inhibited by several amino acids. Proline was not required as an inducer of the systems, which were neither repressed nor inhibited by ammonium. © 1990.
