Abstract:

The present invention is directed to polypeptides that have enhanced alanine 2,3-aminomutase (AAM) activity and/or thermostability relative to the wild-type enzymes that have incidental AAM activity as a result of cross reactivity with alanine. In addition, the present invention is directed to a polynucleotides that encodes for the AAM polypeptides of the present invention, to nucleic acid sequences comprising the polynucleotides, to expression vectors comprising the polynucleotides operatively linked to a promoter, to host cells transformed to express the AAM polypeptides, and to a method for producing the AAM polypeptides of the present invention.

Filed:

Jul 2, 2004

Appl. No.:

10/884121

Inventors:

Richard Chen - La Jolla CA, US
Michelle Chen - La Jolla CA, US

International Classification:

E04H 3/04

US Classification:

186039000

Abstract:

The present invention provides a food transport system comprising a conveyor including a controller that controls the movement of plates of food around the conveyor and determines the circulation time of each plate of food, a food heater and food cooler. The controller automatically diverts individual plates of food to the food heater if they require reheating and automatically diverts individual plates of food to the food cooler if they require cooling.

Appl. No.:

09/679412

Inventors:

Michelle Chen - San Jose CA 95122

International Classification:

A47F 104

US Classification:

221303, 2063159

Abstract:

The present soft article dispenser is comprised of a tube with an open loading end and a constricted dispensing end. The tube is comprised of a rolled up sheet of flexible and collapsible material, such as fabric, with opposite edges which are sewn together. A loading end reinforcing band and a dispensing end reinforcing band are provided at the corresponding ends of the tube. Each reinforcing band is comprised of a rolled up sheet of stronger material, such as leather or vinyl-coated fabric, with opposite edges which are sewn together. The constricted dispensing end is comprised of a disc sewn to the end of the dispensing end reinforcing band. A hole is provided in the disc. A loop is attached to the tube at the open loading end for hanging. Soft articles, such as small items of clothing, plastic bags, disposable gloves, etc. , are stuffed snugly into the dispenser from the loading end.
