| RNA, transfer, met | A transfer RNA which is specific for carrying methionine to sites on the ribosomes in preparation for protein elongation. Initiation of protein synthesis uses trna(f)met in prokaryotic cells and trna(I)met in eukaryotic cells. (12 Dec 1998) |

| phospholipid transfer protein | <protein> Cytoplasmic proteins that bind phospholipids and facilitate their transfer between cellular membranes. May also cause net transfer from the site of synthesis. (18 Nov 1997) |
| modulation transfer function | <microscopy> A mathematical function that expresses the ability of an optical or electronic device to transfer signals faithfully as a function of the spatial or temporal frequency of the signal. The modulation transfer function is the ratio of percentage modulation of a sinusoidal signal leaving to that entering the device over the range of frequencies of interest. The modulation transfer function is usually presented as a graph of modulation transfer function versus log (frequency). For a square wave signal, the function is known as the CTF. Acronym: MTF (26 Mar 1998) |

| cotranslational transfer | <cell biology, molecular biology> Putting the leading end of a polypeptide into the membrane of the endoplasmic reticulum before translation of the rest of the polypeptide has been finished. (10 Nov 1998) |
| heat transfer efficiency | Useful heat output released to the room divided by the actual heat produced in the firebox (17 Dec 1998) |
| nerve transfer | Surgical reinnervation of a denervated peripheral target using a healthy donor nerve and/or its proximal stump. The direct connection is usually made to a healthy postlesional distal portion of a non-functioning nerve or implanted directly into denervated muscle or insensitive skin. Nerve sprouts will grow from the transferred nerve into the denervated elements and establish contact between them and the neurons that formerly controlled another area. (12 Dec 1998) |
| interspecies hydrogen transfer | <biology, ecology> The process in which organic matter is degraded anaerobically by the interaction of several groups of microorganisms in which hydrogen production and hydrogen consumption are closely coupled among species. (09 Oct 1997) |
