| cro protein | <protein> Protein synthesised by bacteriophage lambda in the lytic state. The cro protein blocks the synthesis of the lambda repressor (that is produced in the lysogenic stage and inhibits cro protein synthesis). Production of the cro protein in turn controls a set of genes associated with rapid virus multiplication. (18 Nov 1997) |

| haemagglutinin-neuraminidase protein | <protein> A protein found in the capsid of the Sendai virus which is exceptionally good at binding to the cytoplasmic membranes of many animal cells. The protein is therefore used to make fusogenic vesicles for the purpose of delivering therapeutic drugs or other chemicals directly into cells. (09 Oct 1997) |
| crude protein | Incomplete proteins which lack essential amino acids. (09 Oct 1997) |
| crystalline protein | <protein> The major protein found in the lens of the vertebrate eye, it can be dissolved in water easily. (09 Oct 1997) |
| Csk-like protein-tyrosine kinase | <enzyme> Phosphorylates c-terminal conserved tyr of src family members; from mouse brain; has 52% identity with mouse csk; mw 52 kD; genbank u05210 Registry number: EC 2.7.1.- Synonym: ctk (kinase), ctk gene product, csk-type protein-tyrosine kinase, ntk (kinase), bhk (kinase) (26 Jun 1999) |
| C-terminal leucine protein methyltransferase | <enzyme> Reversibly modifies protein phosphatase 2a by methyl esterification at its c-terminal leucine residues Registry number: EC 2.1.1.- Synonym: tlp methyltransferase (26 Jun 1999) |
| PP5 protein-serine-threonine phosphatase | <enzyme> Has 4 tetratricopeptide repeat (tpr) motifs; similar to ppt1 protein; do not confuse with the placental protein pp5; amino acid sequence given in first source Registry number: EC 3.1.3.- Synonym: pp5 phosphatase, protein phosphatase 5 (26 Jun 1999) |
| pp65 protein | <protein> A protein made by a cytomegalovirus which prevents the cell that the virus has infected from displaying fragments of viral proteins, called antigens, on the cells surface. In this way the cytomegalovirus is able to evade the bodys immune system, more or less permanently. (09 Oct 1997) |
| P protein | <protein> Protein found in large amounts in phloem seive tubes. Appears as thin strands when seen in the electron microscope. (18 Nov 1997) |
| cyclic AMP-dependent protein kinase | Enzymes which attach phosphate groups to the serine or tyrosine amino acids on proteins as a means of regulating the proteins' activity in metabolic reactions. (09 Oct 1997) |
| cyclic AMP-dependent protein kinases | <enzyme> A group of enzymes that are dependent on cyclic AMP and catalyze the phosphorylation of serine or threonine residues on proteins. Registry number: EC 2.7.10.- (12 Dec 1998) |
| cyclic AMP receptor protein | A transcriptional regulator in prokaryotes which, when activated by binding cyclic AMP, acts at several promoters. Cyclic AMP receptor protein was originally identified as a catabolite gene activator protein. It was subsequently shown to regulate several functions unrelated to catabolism, and to be both a negative and a positive regulator of transcription. Cell surface cyclic AMP receptors are not included (cyclic AMP receptors), nor are the eukaryotic cytoplasmic cyclic AMP receptor proteins, which are the regulatory subunits of cyclic AMP-dependent protein kinases. (12 Dec 1998) |
| cyclic GMP-dependent protein kinases | <enzyme> A group of enzymes that are dependent on cyclic GMP and catalyses the phosphorylation of serine or threonine residues of proteins. Registry number: EC 2.7.10.- (12 Dec 1998) |
| cyclic nucleotide-regulated protein kinases | <enzyme> A group of enzymes that catalyses the phosphorylation of serine or threonine residues of proteins and is dependent on cyclic nucleotides. Registry number: EC 2.7.10.- (12 Dec 1998) |
| pregnancy-associated alpha-plasma protein | An alpha 2-macroglobulin, molecular weight approximately 750,000 now believed to be a pregnancy-specific protein. Its plasma levels increase steadily during the second trimester and continue to rise until the end of gestation. (12 Dec 1998) |
