| adenosylcobalamin | A derivative of vitamin B12. Its impaired biosynthesis can lead to methylmalonic acidemia. (05 Mar 2000) |
|---|---|
| adenosylmethionine decarboxylase | <enzyme> An enzyme that catalyses the decarboxylation of s-adenosyl-l-methionine to yield 5'-deoxy-(5'-),3-aminopropyl-(1), methylsulfonium salt. It is one of the enzymes responsible for the synthesis of spermidine from putrescine. Chemical name: S-Adenosyl-L-methionine carboxy-lyase Registry number: EC 4.1.1.50 (12 Dec 1998) |
| adenotomic | Pertaining to adenotomy. Source: Websters Dictionary (01 Mar 1998) |
| adenotomy | <anatomy> Dissection of, or incision into, a gland or glands. Origin: Adeno- + Gr. A cutting, to cut. Source: Websters Dictionary (01 Mar 1998) |
| adenotonsillectomy | Operative removal of tonsils and adenoids. (05 Mar 2000) |
| adenous | Rarely used term for adenose. (05 Mar 2000) |
| adenoviridae | <virology> A family of non-enveloped viruses infecting mammals (mastadenovirus) and birds (aviadenovirus). Infections may be asymptomatic or result in a variety of diseases. (12 Dec 1998) |
| adenovirus | <virology> An icosahedral (20-sided) virus that contains DNA, there are over 40 different adenovirus varieties, some of which cause the common cold. (10 May 1997) |
| adenovirus e1 proteins | The very first viral gene products synthesised after cells are infected with adenovirus. The e1 region of the genome has been divided into two major transcriptional units, e1a and e1b, each expressing proteins of the same name (adenovirus e1a proteins and adenovirus e1b proteins). (12 Dec 1998) |
| adenovirus e1a proteins | Proteins transcribed from the e1a region of adenovirus which are involved in positive regulation of transcription of the early genes. (12 Dec 1998) |
| adenovirus e1b proteins | Proteins transcribed from the e1b region of adenovirus which are involved in regulation of the levels of early and late gene expression. (12 Dec 1998) |
| adenovirus e2 proteins | Proteins transcribed from the e2 region of adenovirus. Several of these are required for viral DNA replication. (12 Dec 1998) |
| adenovirus e3 proteins | Proteins transcribed from the e3 region of adenovirus but not essential for viral replication. The e3 19k protein mediates adenovirus persistence by reducing the expression of class I major histocompatibility complex antigens on the surface of infected cells. (12 Dec 1998) |
| adenovirus e4 proteins | Proteins transcribed from the e4 region of adenovirus. The e4 19k protein transactivates transcription of the adenovirus e2f protein and complexes with it. (12 Dec 1998) |
| adenovirus early proteins | <molecular biology, protein, virology> Proteins encoded by adenoviruses that are synthesised prior to, and in the absence of, viral DNA replication. The proteins are involved in both positive and negative regulation of expression in viral and cellular genes, and also affect the stability of viral mRNA. Some are also involved in oncogenic transformation. (12 Dec 1998) |
