2-Aminobenzenesulphonic acid (2AS) is degraded by Alcaligenes sp. strain O-1 via a previously detected but unidentified intermediate. A mutant of strain O-1 was found to excrete this intermediate, which was isolated and identified by m.s., 1H- and 13C-n.m.r. as 3-sulphocatechol (3SC). Proteins from cell extracts of strain O-1 were separated by(More)
It had previously been shown that dissociated cell cultures from chick embryo spinal cord have a high affinity uptake system for the neurotransmitter gamma-aminobutyric acid (GABA) and make functional inhibitory synaptic contacts as determined by electrophysiology (Farb et al., 1979). It is shown here that these cultures can synthesize GABA from added(More)
