Two uptake systems for phenol are identified in Trichosporon cutaneum. One is an inducible, high-affinity system, sensitive to protonophores. It is induced coordinately with phenol hydroxylase but can operate independently of phenol metabolism. The other is a constitutive, low-affinity system with different specificity and different pH optimum. It is not sensitive to protonophores.
在皮状丝孢酵母中鉴定出两种苯酚摄取系统。一种是可诱导的高亲和力系统,对质子载体敏感。它与苯酚羟化酶协同诱导,但可独立于苯酚代谢发挥作用。另一种是组成型的低亲和力系统,具有不同的特异性和不同的最适pH值。它对质子载体不敏感。
