[Antiandrogenic pharmacotherapy of sexual offenders and home leave steps in the forensic psychiatric hospital Berlin].

Objective: Evaluation of the relationship between antiandrogenic therapy of sexual offenders and home leave steps in a forensic psychiatric hospital.

Methods: Retrospective evaluation of all sexual offenders (n = 79) who were treated in the forensic psychiatric hospital Berlin between the 1.1.

Biosynthetic gene cluster of the herbicide phosphinothricin tripeptide from Streptomyces viridochromogenes Tü494.

The antibiotic phosphinothricin tripeptide (PTT) consists of two molecules of L-alanine and one molecule of the unusual amino acid phosphinothricin (PT) which are nonribosomally combined. The bioactive compound PT has bactericidal, fungicidal, and herbicidal properties and possesses a C-P-C bond, which is very rare in natural compounds. Previously uncharacterized flanking and middle regions of the PTT biosynthetic gene cluster from Streptomyces viridochromogenes Tü494 were isolated and sequenced.
