| sucrose alpha-d-glucohydrolase | <enzyme> An enzyme hydrolyzing sucrose and maltose; in a complex with isomaltase; hence, hydrolyzes both sucrose and isomaltose; found in the intestinal mucosa; a deficiency of this enzyme results in defective digestion of sucrose and linear a1,4-glucans.

| d(-)-alpha-aminobenzylpenicillin | <drug> Penicillin derivative with broad spectrum activity, ampicillin resistance is often used as a marker for plasmid transfer in genetic engineering (for example pBR322 is ampicillin resistant). (13 Nov 1997) |
| deficiency, alpha-1 antitrypsin | An inherited disease with little or no production of an important protein, alpha-1 antitrypsin. The lack of this protein leads to damage of various organs, mainly the lung and liver. The disease may become apparent at a very early age or in adulthood, as shortness of breath or liver-related symptoms (jaundice, fatigue, fluid in the abdomen, mental changes, or gastrointestinal bleeding). There are several options for treatment of the lung disease, including replacement of the missing protein. Treatment of the liver disease is a well-timed liver transplant (12 Dec 1998) |
| delta-(alpha-aminoadipyl)cysteinylvalinedisulfide reductase | <enzyme> Broad range disulfide reductase from streptomyces clavuligerus; requires NADPH; involved in the production of beta-lactam antibiotic such as penicillins and cephalosporins Registry number: EC 1.6.4.- Synonym: bis-acv reductase, delta-(-l-alpha-aminoadipyl)-l-cysteinyl-d-valine disulfide reductase, acv disulfide reductase (26 Jun 1999) |
