摘要： An extracellular leucine aminopeptidase was isolated from the culture medium of Streptomyces therrnonitrificans which is a Zn.sup.2+ -dependent metalloenzyme which comprises an amino acid sequence Lys-Phe-Ser-Lys-Lys-Phe-Asn-Glu (SEQ ID NO: 3) at the N-terminal thereof, and amino acid sequences of Glu-Pro-Gly-Thr-Gly-Ala-Leu-Glu-Pro (SEQ ID NO: 4) and Asn-Pro-Asp-Ile-Val-Tyr (SEQ ID NO: 5) at other regions thereof. The aminopeptidase has a pH optimum of 7.5 to 9.0, a temperature optimum of 30.degree. to 50.degree. C., and an apparent molecular weight as determined by sodium dodecyl sulfate polyacrylamide gel electrophoresis under reducing conditions of 41 to 45 kDa, and as determined by gel filtration under native state conditions of 36 to 40 kDa.

摘要： System for establishing a surface shape. The system includes a compliant substrate including the surface and having a reverse side, and a plurality of discrete actuators engaging the reverse side and arranged in a selected pattern to control the surface shape as individual discrete activators are activated. It is preferred that the actuators have multiple discrete stable states of elongation. A particularly preferred embodiment uses actuators that are binary with two stable states of elongation.

摘要： A temperature monitoring system comprises a sensor for measuring the surrounding temperature, a timer for generating clock data, a controller for reading temperatures at predetermined intervals and storing selected temperature data and corresponding time data in memory, input switches for entering commands and data, a data display, and first and second alarm indicators. The controller operates in predetermined steps to activate the first alarm to indicate a current alarm condition and to activate the second alarm to indicate a past alarm condition. The controller selectively switches the display between normal and alarm modes to show differing time and temperature data depending on the temperature conditions monitored. The user may review alarm histories, including total alarm time and, for each past alarm period, maximum temperature, starting time and alarm duration, which have been calculated and stored.
